Ultrasonic sludge sensor.

• ATEX certified
• High or Low level alarm
• Failsafe design

Ema Signal type ES8 is an ATEX certified ultrasonic sensor for use to detect sludge, sand or other type of solid material in tanks containing liquids as wastewater tanks etc.

The sensing element consists of a ultrasonic transmitter and a receiver. The unit is transmitting ultasonic pulses which travels to the receiver, as long as the there is only water between the transmitter and the receiver the unit will be able to detect the signal. As soon as the transmission is blocked by solid material the unit will be able to give an alarm via the connecteed control unit typically a ema signal type ES3 ot type OSA.

The sludge probe is mounted at a suitable height in the tank and connected to the control unit. The control unit is universal and can be used for both high or low level alarms. The design is failsafe which mean that the unit will give alarm for different faults in the sensor connection circuit.

The control unit has one voltage free switching relay output which can be used for lamp connections or pump control etc.
