KL1 Cable Junction Box for Submersible Level Transmitters

Robust cable junction box for terminating vented electrical cable from a 2 wire submersible hydrostatic level transmitter. The inside of the IP66 sealed box is vented to the ambient outside air via a PTFE filter to ensure the level sensor is properly vented to compensate for atmospheric pressure.

The KL1 enclosure is made from a die cast aluminium with a grey powder coating. The internal environment is sealed to IP66 to prevent dust or moisture ingress.  A PTFE filter pressure balance is incorporated into the enclosure wall to provide a vent path for the submersible sensor cable. 

Two M16 x 1.5 polyamide cable glands with NBR seals are fitted to the underside of the termination box to provide strain relief and an IP68 seal for the cable entry of the over-ground and submersible sensor cable.  The wires are terminated inside via vertical screw clamps which can accommodate wire with diameters up to 2.5mm2. 

In addition to providing a junction for a 2 wire 4-20mA output signal from a submersible borehole level sensor the KL1 termination box also has the options for including a PT100 transmitter and over-voltage discharge protection to 10 kiloamps related to nearby lightning strikes.
