SPM Submersible Pump Monitor

The SPM Submersible Pump Monitor from ATC Diversified Electronics is a dual function alarm relay designed to monitor shaft seal and stator temperature of a submersible pump motor, providing early warning of machinery failure to reduce downtime and maintenance costs.

The SPM Submersible Pump Monitor operates from a standard 120 VAC 50/60 Hz supply voltage, with reliable operation over 10 million continuous duty cycles. The series detects leaks by either resistive float switch or a pair of conductive probes installed in the seal cavity, while over-temperature is detected by a normally-closed low-temperature switch that is mounted on the stator, with LED’s that indicate green for “normal” and red for “leak” and “over temperature” condition values. The SPM series also incorporates the use of a bi-stable relay which can retain its position during power failures or energy surges. The relay automatically resets following leakage detection when the fault condition has cleared. Sensor voltage is 12 VDC (model AEE) and 9 VDC (model AEA). Units are UL listed and include a 10-year comprehensive product warranty.

Seal leakage is detected by either a resistive float switch or a pair of conductive probes installed in the seal cavity. Over-temperature is detected by a normally-closed-low temperature switch mounted on the stator. The over-temperature function of the SPM Submersible Pump Monitor incorporates a bistable relay that retains its position during power failures.

SPM series is ideal for use in OEM; potable or wastewater sump pump; industrial or municipal pump monitoring; control package manufacturing; and general industrial seal leak and over-temperature detection applications.
