|
The AX-WLD-DT-M is a water level alarm module. It is intended for monitoring the condensate levels in drip trays on air-conditioning units. The unit comprises two stainless steel probes and integrated electronics to transmit the signal over Modbus RTU. The probes are mounted at the level required to generate an alarm signal. The excitation signal generated by the unit for the sensor connections ensures that the probes do not degrade when exposed to damp for long periods. |
