General Mechanical Pressure Switch Model 323

General Mechanical Pressure Switch  Model 323




BCM 323 series pressure switch is a low-cost device of general purpose for industrial automation or process control application. The 323 pressure switch is composed of a common spring tube and associated with moving parts of relevant electrical contacts. These parts are isolated and located inside the housing.

Two types of 323 pressure switches are available: initially open (type O) and initially closed (type C). Take type C as an example (refer to the left diagram below), when there is no pressure input (zero pressure), the electrical contacts of 323 are connected to each other, which is corresponding to an “CLOSED” state of the device, and the electrical resistance is zero between the associated contacts of 323. If the input pressure increases gradually the upper limit of pressure (P2), the moving parts enables switching and results in the electrical contacts disconnected, referred to an “OPEN” state of the device. In the “OPEN” state, the electrical resistance is infinite between the associated electrical contacts of 323. Once the input pressure decreases gradually from P2 down to the lower limit of the pressure (P1), the moving parts of the device is switched back to its initial position, having the electrical contacts connected again. Therefore, the 323 comes back to its initial “CLOSED” state, restoring the zero electrical resistance between the associated electrical contacts of 323. As the electrical contacts of 323 can be disconnected and connected again by the variation of input pressure, with 323 series pressure switches, one can disconnect and connect an actuator in an industrial automation system.
