The P88V Economical Vacuum switches are typically used in applications where reliable switch control supersedes accuracy of set point. Controlling on and off functions for fans and pumps where one may need a wide differential to prevent over-cycling is an ideal application use for the P88V.
The P100V High Accuracy Low Vacuum Environment Vacuum switches are ideal in low vacuum applications where precision of setpoint must be high and repeatability low. These switches are com¬monly used in natural gas well heads, natural gas generator sets, and air applications like forced draft blowers. The P100V can be used both in dry indoor applications or within an enclosure.
The P117V Stainless Steel Miniature Vacuum switches are sharp, highly versatile devices that can be used in hundreds of OEM and routine mechanical applications. It is among our most popular switches given its durability and diverse set point options.
The P117LV NEMA 4 Stainless Steel Vacuum Switches are the weather-proof, liquid-resistant version of the P117V. The NEMA 4 rating makes these rugged switches suitable for outside applications or in areas of condensing humidity. Unlike the P117V, the P117LV set point is factory set to customer specification and is non-adjustable.
The W117V Ultra Pure Stainless Steel Vacuum Switches have all welded stainless steel interiors which are Helium leak checked to pass 4 x 10-9 Std CC/Sec. These switches are used in silicon wafer ovens, numerous medical devices, and other applications where even the slightest impurities are not tolerated.
The W117LV NEMA IV Rated Ultra Pure Stainless Steel Vacuum Switches have all welded stainless steel interiors which are Helium leak checked to pass 4 x 10-9 Std cc/sec. These are the weather-proof, liquid-resistant version of the W117V suitable for outside applications or in areas of condensing humidity.
The P119V Zinc Diecast Body Vacuum Switches are the inexpensive version of the P117V and recommended for indoor OEM use. It is commonly used in the medical field and as a safety switch in numerous applications. The compact nature of these switches make them ideal for tight spaces.
The J205V High Vacuum Low Set Point Vacuum Switches are among our most versatile offering, affording the end user an extensive operating environment and a wide range of set point optionality. These switches can be exposed to severe vacuum conditions without compromising integrity or switch functionality.
The J205LV NEMA 4 High Vacuum Low Set Point Vacuum Switches are among our most versatile offering, affording the end user an extensive operating environment and a wide range of set point optionality. These switches are the NEMA 4 rated weather-proof, liquid-resistant version of the J205G, suitable for outside applications or in areas of condensing humidity.
The P803 Low Pressure OEM Transmitters are affordable, compact transducers suitable for pressure ranges up to 600psi. These devices have stainless steel wetted parts, and are ideal in applications where space is at a premium and reliability and stability are critical. A wide range of electrical outputs as well as electrical and pressure connections make these units a perfect fit for numerous OEM applications and media.
The P806 Series Pressure transmitters are compact, yet highly durable sensors with pressure ranges from 0 to 30,000 psi and proof pressures up to 45,000 psi. These units have 304 stainless steel housings with 17-4 PH stainless steel wetted parts, allowing for more severe environments and operating temperatures up to +257°F (+125°C). A highly diverse selection of electrical and pressure connections, as well as output signals, allow for customization across a wide range of applications and media.
The P805 Industrial Pressure Transducers are compact, rugged pressure transmitters with silicon piezoresistive sensors packaged in stainless steel housing. These precision engineered devices provide absolute, gauge, and sealed gauge pressure measurement up to 8700 psig with a variety of output signals available. These devices are suitable for applications across process control, including hydraulic systems and valves, refrigeration and HVAC controls, level measurement, and test equipment. In addition to pressure ranges and output signals, a wide range of process and electrical connection options are available to meet any end user demands.
