Pressure Switches
Baratron Gauge Pressure Switch
The MKS Types 41, 42, 51 and 52 Vacuum, Atmospheric and Pressure Switches offer accurate and reliable protection for vacuum equipment, atmospheric switching, and vacuum/pressure processes. Designed for applications where a DC signal output is not required, these switches provide relay outputs that are readily interfaced with alarms, valve actuators, computers, process controllers, load locks and other protection devices.
The Type 41/42 switches reference atmosphere while the Type 51/52 switches reference vacuum. The Type 41/42 switches are often used to ensure a loadlock pressure has equilibrated to local atmospheric pressure before opening the door. The trip point on MKS' atmospheric switches can be set to trip above, below (reverse calibration), or exactly at current atmospheric pressure. Applications for the 51/52 switches include soft pumping, gas box switching, and safety interlocks.

The SPC98 dry and flush mounted ceramic pressure sensor uses an aluminum oxide ceramic sensor as a "dry cell" that is extremely resistant to overload, aggressive mediums, extreme min/max temperature, applications with solid particles and low pressure ranges. These transmitter's are made in either 316 S.S. or Hastelloy C and provide a 4-20mA output signal. The SPC98 is designed to be installed at the bottom of the tank.
FEATURES
*Loop powered, 4-20mA signal output
*Measuring ranges -1 to 580PSI (-1 to 40 bar) gauge /absolute
*Ideal for waste water or other applications with "dirty" medium
*Rugged and compact design- Body entirely 316 S.S. or Hasteloy C
*High accuracy, Excellent repeatability & Temperature compensated
*3A approved
The actual measuring range of the SPC98 sensor is determined by the thickness of the ceramic diaphragm, which if overloaded, stops on the ceramic substrate without sustaining damage. Ceramic cells do not expand and contract nearly as much as metal, ensuring good temperature stability. Common features of the SPC98 are low hysteresis, high repeatability, immunity to the effects of process builds up and outstanding resistance to chemical attack.
