The set includes SQUEALER controller and Oiler probe. The set is build on the basis of a modern microprocessor devices for continuous monitoring the status of selected probes. The basic parameters of the controller is 1 input, 1 relay output, LEDs indicating normal state, failure status and alarm status, buzzer generating an alarm signal, alarm output, relay output, activated at the time of alarm.

SQUEALER-1
– 1 input (overflow, fat layer thickness or oil level, the level of sludge)
– 1 output for BMS (potential-free relay)
– 230V power supply
– Hermetic housing used outdoor
– Dipswitch (programming using dipswitches)
– Optical and acoustic signals of troubles and alarms on the front panel
– Sensor diagnostic (opening / short circuit)

OILER
(oil, fat, petroleum probe, with 5m cable, ATEX, 4-20mA)
Oil level measurement; measurement of petroleum substances; fat layer thickness measurement; conductivity technology; ATEX certified. Output signal 4-20mA.

Front panel description.
– LED green – probe is OK
– LED lights alternately green and red – ALARM
– LED lights alternately yellow and red – FAILURE
– Short press – cancel acoustic alarm signal.
– Long press of the button – device test (LED, BUZER and RELAY). Test possible only in normal state (without alarm).
