Industrial Process Control Instruments

• Pressure Switches are available in two basic categories: Fixed Differential Pressure Switches, Adjustable Differential Pressure Switches, Flameproof Pressure Switches and Digital Pressure Switch.
• In any application when the Digital signal is required as soon as the process exceeds the set pressure limit in the Switch (either on rising side or on falling side), the Fixed Differential type Pressure Switches are used. . i.e. as Safety device or, for interlocking purpose Fixed Differential type Switches are used.
• In some applications the pressure in the vessel has to be controlled between two limits higher and lower. The switch which has a facility to set the gap between higher set point and the lower, our Adjustable Differential type Pressure Switches are to be used.
• We have a wide range coverage from 15 mm Wc up to 600 bar. All these switches are available in IP 40, IP 54, IP 65, IP 66 and flameproof enclosures.
• These pressure switches can be provided in pressure housing materials like Aluminium, Brass, MS and SS 316 or, some special material also like Alloy or, Teflon. The sensing element can be in Teflon, Neoprene, SS 316L or, piston.
• Pressure Switches can also be provided with 2 SPDT contacts. Fixed Stage Differential type Pressure Switches and Adjustable Differential type Pressure Switches. All these switches can be provided with varieties of Diaphragm Seals. Using the specific Diaphragm Seals the switch can be used for viscous mediums or, even for hygienic applications.
• The Pressure Switches can also be provided with Digital Readout. These Switches can also have have 4 to 20 mA output

• Vaccum Switches are available in two basic categories based on ranges: Full vacuum range and Low vacuum range. In any application when the Digital signal is required as soon as the process exceeds set vacuum limit set in the Vacuum Switch (either on rising side or on falling side) the Fixed Differential type Vacuum Switches are used.
• In case of Vacuum control applications, Adjustable Differential type Vacuum Switches are used.
• We have a wide range coverage from 100 to 760 mm Hg. All these switches are available in IP 54, IP 65, IP 66 and flameproof enclosures.
• In case of Low Range Vaccum applications we offer Low Range DP Switches, where in the high pressure port has to be kept open and vacuum has to be connected to the Low Pressure port. The range covered is from 15 mm Wc up to 2500 mm Wc.
• These Vacuum switches can be provide in pressure housing materials like Aluminium, Brass, MS and SS 316 or, some special material also like Alloy or, Teflon. The sensing element can be in Teflon or, Neoprene..

• When the change in pressure has to be sensed and analogue output is required in terms of mA or mV, Pressure Transmitters or, Pressure Transducers are used. Pressure Transmitter and Pressure Transducers are normally available with SS 304 wetted parts, but we can also give those in SS 316 as well as Teflon contact parts. We also have the same in hygienic versions also. We have the range coverage from 100 mm Wc up to 1000 bar in IP 65, IP 66, ATEX as well as flameproof enclosure. These can be provided either blind type or, with Digital Readout. We provide then in accuracy of 1%, 0.5%, 0.25% as per customers requirement.

• Differential Pressure Gauges (DP gauges) works on Magnetic Coupling Principle. Diaphragm type DP Gauges and Piston type DP Gauges are available in our range, whcich covered range from 15 mm Wc up to 10 bar These Differential Pressure Gauges are suitable for very high static pressures. Teh Pressure chamber is isolated from teh DP Indicating chamber., so the DP Gauge is safe for the usage. As these is no bourden tube in these type of gauges, damages and zero shift is also not possible in these gauges. All these gauges are available with varieties of wetted parts like Aluminium, Brass, SS, Monel, Industrial Plastic or any special as per the specific requirement. DP Gauges can be provided in dial sizes like 50 mm, 65 mm, 80 mm, 100 mm and 150 mm.
• Differential Pressure Gauges are mainly used in the applications like filtration systems, HVAC, Heat exchangers, flow measurement through Orifice plate, Liquid Level measurement in pressurized tanks etc.
• One or, Two nos. field settable Switches are possible along with these DP Gauges.

• Differential Pressure Switches are normally used in the applications where the digital signal is required when Differential Pressure crosses the set DP in the DP Switch, either on rising or on falling side. We provide this contact through Micro Switches or Reed Switches. DP Switches are available in wetted parts like Aluminium, Brass, SS, Industrial Plastic, Monel or any special as per process requirements. The DP switches are also available with varieties of Diaphragm Seals. Ranges available in Differential Pressure Switches are from 15 mm Wc up to 10 bar. DP Switcyes are avaiable for high static pressure applications also known as High Static Pressure type Differential Pressure Switches are also available. Differential Pressure Switches (DP Switches) are available in IP 40, IP 54, IP 65, IP 66 and flameproof enclosures. Combination of DP gauge with switch also can be provided.

• Flow is considered to be one of the important parameter in process industry. Most of the process in the industry like Food, Chemical, Pharmaceutical, Petrochemical, Textile, Tile manufacturing, Automobile, Automation etc. depends upon the variation of the flow and it is necessary to measure, indicated and control the flow of different mediums. Varieties of Flow Meters available like, Variable Area Flow meters, Metal Tube Rota Meters, Turbine Flow Meters, Rotary paddle type Flow meter, Electro Magnetic Flow Meters, Positive Displacement flow meters, Ultrasonic Flow Meters etc. Depending on the type of application the type of meter has to used. For clear liquids Variable Area Flow Meters, Turbine Flow Meter, Rota Meter, Rotary Paddle type Flow meters are used. But for costly fluids like Diesel, Petrol, solvents etc.Positive Displacement Flow Meters i.e. PD Meters are recommended. Rotating Paddle type Flow Meters also avaialble in Battery operated versions. Rotating Paddel type Turbine Flow Meters, PD Meters and Metal Tube Rota Meters can be provided with options as Flow Rate Indicator (for instantaneous flow), Flow Totalizer (Rate of Flow with Totalizer), Flow Meter with Batcher or, Relay and Flow Rate & Total Indictor with Transmitter. We also have the Ultrasonic Flow Meters for non contact type liquid flow measurements.

• For positive detection of fluid flow - Flow Switches are used. Flow Switches are available for liquids & Gases. Like water, kerosene, lubricating oils, coolants, air etc. Flow Switches are used to ensure availability of desired flow or no flow in the system in order to prevent or to control any disaster in the industry. Magnetically or Micro Switch operated flow switches are available from 6 mm in size. Magnetically operated Flow Switches (Miniature Flow Switches / Blind Flow Switches, Indicating type Flow Switches / Flow Indicating Switches) are normally used for low flow capacities max. up to 150 LPM. Micro Switch operated Paddle Type Flow Switches are an ideal solution for higher flow rates and bigger line sizes. Paddle type Flow Switches are available in 2 types - Bellow type Paddle Flow Switches and Magnetic Repulrion type Paddle Flow Switches.

• According to the type of applications, varieties of level switches can be provided. For different types of clear liquids Float type Level Switches or Capacitance type Level Switches, for conductive liquids Conductivity type Level Switches are used. For dry powders and pallets Rotating Paddle type Level Switch, Vibrating Fork type Level Switches or, Vibrating Rod type Level Switches are recommended. RF Admittance Level Switches as well as LBFS Level Switches or, LFFS Level Switches, FLS Level Switches can be used for dry powders, pallets as well as slurries & pastes., effluents, sewageetc. LBFS Level Switches are used for Hygienic applications. For dry powders and granules Diaphragm type Level Swiches are also available.
• Level switches are available on the basis of the suitability of mounting type and orientation of mounting i.e. Side mounted or, Top mounted. Wetted parts in Level Switches are in Industrial Plastic, PVDF, Teflon, SS 304, SS 316 or any special as per the customer’s requirement..
