Barksdale Controls CD2S-M150SS-S1 Dialmatic Pressure Switch

The Barksdale CD2S-M150SS-S1 Dialmatic Pressure Switch is a diaphragm-type control device in Barksdale’s Dialmatic line, designed for precise low-pressure monitoring with dual-setpoint capability. It covers a 1.5 to 150 psi working range, with the M150SS designation indicating two adjustable setpoints and dual SPDT contacts for two independent switching actions. As a stripped (S) variant in the CD2S family, the unit is intended for integration into panel-mounted or compact installations where a dial-adjustable, two-point pressure switch is desirable. The Dialmatic configuration provides straightforward mechanical adjustment via a calibrated dial, enabling repeatable activation and deactivation pressures within the 1.5–150 psi window. Two SPDT outputs allow coordinated control of two circuits from a single sensor, supporting applications that require simultaneous monitoring and signaling or sequencing of separate devices. In systems using pneumatic, hydraulic, or process equipment, this compact switch delivers reliable pressure-triggered control without the need for complex electronics, making it suitable for pump start/stop logic, actuator control, or limit/dwell signaling in automated setups.
