Pressure Switches and Temperature Switches
 B-Series
General purpose switches for most industrial and process applications.
Models are available for steam and fuel pressure limit controls on boilers and
burner. Ideal for compressors turbines, filters, blowers, etc.
Features:
Enclosure
 | Watertight epoxy coated aluminum NEMA 4, 4X or explosion proof NEMA 7/9 |
Switch Function
| Single setpoint, fixed deadband, SPDT (or) |
| Single setpoint, fixed deadband, 2 SPDT |
Wetted Materials
| Stainless steel and Buna, TeflonŽ, or VitonŽ (or) |
| All welded stainless steel (or) |
| All welded Monel |
Setpoints
| Pressure: Vacuum through 3,000 psi |
| Temperature: -40°F through 750°F |
| Differential Pressure: 4" H2O
diff. through 600 psid |
 L-Series
Easy to use L-Series switches are specifically suited for the OEM seeking
more features in a snap acting switch. Single or dual setpoints and fixed
or adjustable deadband models with many wetted materials and electrical ratings
are offered. This snap acting switch also replaces older mercury models
and is cost effective. L-Series switches are ideal for blowers,
generators, scrubbers, precipitators, compressors and turbines.

| Differential Pressure: 4" H2O
diff. through 400 psid |
 P-Series
More varieties and more features are available in the highly reliable
P-Series switch which is especially suited for process and refinery
applications. Dual chamber design allows setpoint changes to be made
safely even with power connected. Features include NEMA 4 or NEMA 7/9
enclosures, with single or dual setpoints, fixed or adjustable deadbands, with
many wetted materials and electrical ratings. Optional, all-welded
stainless steel or Monel actuators are ideal for applications requiring NACE or
firesafe conformance. Option UL listed, hermetically sealed switch
contacts improve safety and reliability.
