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.
