836T-T352J

The 836T-T352J, which is produced by Allen-Bradley, is an electro-mechanical pressure switch. This pressure switch is triggered by an external pressure signal connected to the input port. Equipped with either a quarter-inch or even a 38-inch female NPT threaded port, it's intended for use in industrial applications where external connections must mirror the existing conditions. Allen Bradley's 836T-T352J electromechanical pressure switch utilizes bellows made of copper alloy that may change position due to a system of levers and springs. These components are examples of mechanical devices intended to automatically activate the electrical connections at a set point chosen by the end-users during calibration. Both the trigger and reaction, as well as reset set points are readily changeable through a series of screws and locking components labeled appropriately on the device.

In addition to compressed air and non-corrosive liquids, hydraulic oil and water are among the pressure media that the Allen-Bradley 836T-T352J electromechanical pressure switch is capable of handling. Special modifications may make it possible for this switch to operate in hazardous environments, although corrosive pressure media will cause damage to the copper alloy bellows in the process. In the case of an outdoor installation of this 836T-T352J pressure switch, sufficient protection from strong sunlight and moisture must be given, as well as the availability of regular maintenance. Coupled with an oil-tight plastic isolator material that is welded together, the device's robust and durable metal casing provides exceptional security against water damage. However, in places where flooding occurs on a regular basis, these precautions should not be regarded as sufficient safeguards against disaster.
