SPM Dual Channel Seal Failure Alarm
  • Monitors Shaft Seal of Two (2) Submersible Pump Motors
  • Connects to Conductive Probe in Seal Cavity
  • Adjustable Sensitivity
  • LED Indicates Output Relay
Product Detail:
The ATC Diversified Electronics SPM Series dual seal failure module is a specialized control for monitoring the shaft seals of two submersible pump motors. Leaks are detected by sensing the conductivity of the contaminating fluid through probes installed in the seal cavity. When a seal begins to leak, the seal failure module energizes one of its SPST output relays indicating that the seal needs to be replaced before the motor is damaged. The sensitivity of the probe inputs is field adjustable. When the resistance between one of the probe inputs and the common connection drops below the sensitivity setting, the corresponding output relay and LED are activated.
