Electronic Pressure and Temperature Switches

United Electric ControlsAC power supply has been added to the One Series Electronic Switch Platform, making this series designed to solve the challenge of monitoring critical pressure and temperature thresholds for alarming, shutdown and redundant control. The switch can be utilized with either AC or DC powered circuits. This series combines several monitoring functions traditionally performed separately by transmitters, switches and gages with just a single process connection.

The AC power module provides 115 VAC input/output through an integral AC power supply. This enables users to connect AC power and loads directly to the platform. It also has both high voltage (AC) and low voltage (DC) terminal blocks. Dual conduit entries allow for separation of high and low voltage signals.

A digital display provides both a real time indication of process variable and a means for operator field adjustment of set point and deadband. The product communicates its health (IAW) and the state of the switch remotely over a standard two wire discrete digital connection. If analog trending data is needed, an optional 4-20 mA output can be added. The device features fast switch response on either rising or falling pressure or temperature, and can handle ranges to 6,000 psi or 1000°F. Set point and deadband are adjustable to cover the full operating range. It is suitable for critical alarm and shutdown applications in harsh or hazardous environments.
