WIRING

Check the distance between the sensor and the indicating/controlling device. If necessary, the

sensor can be ordered with a longer cable attached.

POWER SUPPLY

Be sure to use a 24 V DC (22 mA) power supply.

MECHANICAL INSTALLATION

All sensors come with a 1m cable and a mounting nut. The sensor can be mounted on

brackets or cut outs of your own design, or you can use the fixed and adjustable mounting

bracket accessories which are shown below.

AIR/WATER COOLED HOUSING

The air/water cooled housing shown below allows the sensor to withstand high ambient

temperatures. It is equipped with two 1/8" BSP fittings. Water temperature should be

10°C to 27°C for efficient cooling. Chilled water below 10°C is not recommended. To avoid

condensation, the air purge collar should be used with the water-cooled housing. Water flow

rate should be 0.5 to 1.5 litres/min. Adjust the flow rate and temperature of the cooling fluid

to keep the sensor body between 0°C and 70°C.
