We are the leading manufacturer, exporter and suppliers of Air Operated Diaphragm Level Liquid Switch in Maharashtra, India. This is a simple, cost-effective level switch which is manufactured using the finest quality raw materials. It can be easily installed and has been proven to maintain a long shelf-life. This switch is used for highly-viscous liquids, sewage & slurry.   Details :Simple, Cost-effective and easy to install switch with minimal maintenance  Range - upto 2000mm Wtd Parts - PP, SS316 Max Temp - 60oC Max Pressure - Atm Contact - 5A, 250VAC x SPDT Enclosure - Cast Al x IP66 Applications : Highly-Viscous Liquids, Sewage & Slurry

Measure pressures relative to atmospheric pressure and are divided into three main groups, each group being based on a different measuring principle. The majority of our pressure switches have a SPDT micro-switch fitted, including versions in ATEX approved housing, but where double pole switching is required, we can supply a range of pressure switches fitted with a DPDT micro-switch.Diaphragm Switchesconsists of either a corrugated metallic diaphragm or a synthetic rubber diaphragm. Metallic diaphragms are more versatile as the diaphragm can be treated to meet the majority of chemical applications, where as synthetic rubber diaphragms are limited to the compatibility of the synthetic rubber. The maximum pressure that diaphragm switches normally operate is 42 bar but they can be overload protected to 200 bar. Diaphragm pressure switches can also be set to switch in vacuum.Piston Switchesconsists of a piston that has a o’ring seal that is either mounted on the piston or in the body. Piston switches are normally used where the pressure is above that of diaphragm switches. Piston switches should not be used on gasses due to the inherent high friction that an o’ring has especially when pressure is not applied for a period of time. Piston switches are for high-pressure applications of up to 700 bar.Bourdon Tube Switchesconsists of a formed tube with one end fixed and the other end free to deflect under pressure and operate an electrical switch. Bourdon tube switches should be used for high pressure gas applications. Pressure ranges up to 600 bar can be supplied.

We are offering air operated diaphragm switch. Compact, versatile, economical, 2mtrs range with 1 spdt contacts for sewage, slurries, viscous liquids, dirty oils in tanks open to atmosphere.( 60°c).

• Applications: Chemical, petroleum, food and drug processing industries. Used indoor, outdoor or in explosion-proof area.

Weatherproof and Explosion-Proof in One Economical Enclosure Extremely rugged construction assures excellent reliability in chemical, petroleum and industrial plants. New design also provides burst pressure protection to 3000 psi (206 bar). The rolling diaphragm design maintains a constant effective area to minimize friction. This results in a minimum deadband as low as 5% of full scale. Since many applications require higher deadbands, the SA1100 includes a separate adjustment of this when necessary. A pump being used to control liquid level in a tank would be a typical situation where this feature would be important. Both setpoint and deadband adjustments are protected, yet clearly visible behind a clear polycarbonate window and are fully isolated from the electrical components for additional safety. A 716" open-end wrench is the only tool required to change settings. Terminal blocks are provided for switch wiring connections and both internal and external ground screws are included. Standard housing is weatherproof to NEMA standards 1 through 4X and 13; explosion-proof to NEMA 7, Class I, Groups B, C & D; NEMA 9, Class II, Groups E, F & G. Optional construction adds drain to meet NEMA 3R IP54.
