Chemical Seal
Switzer offers a variety of Chemical Seals for use with its range of Pressure, Differential Pressure Switches and Differential Pressure Indicators, for applications where corrosive, highly viscous or slurry process media are encountered.
Since total isolation is provided by the chemical seal, hazard of leakage of corrosive and dangerous chemicals is reduced.
The design principles applied to Switzer Chemical Seals ensure process pressure variations to be precisely transmitted to the instrument’s sensing element without its coming in contact with the process medium.
The seal, capillary in the case of remote seals and pressure sensing element of the instrument are carefully filled with suitable pressure transfer fluid. Any pressure applied to the seal diaphragm is hydraulically transmitted to the pressure sensing element.
Besides the protection provided by isolating the process medium from the instrument, the chemical seal can also be used as a protection against high process temperatures, pulsations / vibrations.
A Chemical Seal extends the service life of the instrument, eliminates repetitive replacements and reduces maintenance costs. Thus its initial investment cost will be recovered in a short duration.
Electronic Pressure Switch
Electronic Pressure Switch Model 711 is ideal for precise process pressure measurement. This instrument is built with high accurate piezo-resistive pressure sensor with 316SS diaphragm which is suitable for media like non-corrosive liquids and air.
A wide range of pressure readings with optimum resolution are indicated through a large LCD display with back light. Two or Four independent setpoint is provided with SPDT relay output for on-off control function.
In addition, this instrument provides 4–20 mA DC analog current output. The output current range is programmable within the instrument calibrated range.
Operational settings are done through 3 push switches accessible upon removal of cover or on the front through membrane keypad.
The entire circuitry is housed in a cast aluminium, IP65 compliant weatherproof enclosure suitable for surface / wall (or) pipe mounting.
Temperature Switches Direct
Type AST Temperature switch has been specifically designed for use on Diesel Locomotives to safeguard the engine from damage that could be caused by excessive heat. However these switches can be used for other applications also. These switches are of direct mounting design.
The thermal sensing element of AST temperature switch consists of a metallic bellows and sensing bulb. This thermal element is filled with a partial vapour charge , the pressure of which rises with the increase in temperature at the bulb. When the temperature exceeds the preset value , the pressure in the thermal system increases and overcomes an opposing spring force to actuate an electrical microswitch. The entire assembly is housed in a uniquely designed die cast aluminium enclosure which allows ease of installation and wiring .
