Liquid Level Switches

Optomax Digital Series

a) Above +85°C, Trogamid is suitable for use in water based liquids. Oil based liquids can cause deformation of the sensing

tip and must be tested for compatibility.

b) Before use check that the fluid in which you wish to use these devices is compatible either with Polysulfone or

Trogamid®.

c) Voltages applicable to output value stated.

CIRCUIT DIAGRAMS In order to suit any application, these sensors have been designed with various output circuit configurations. CAUTION: Take care when connecting loads. The minimum load impedance should not exceed Vs/max output current. Note: Shorting the output to Vs or 0V will result in irreparable damage to the sensor. ORDER INFORMATION Generate your specific part number using the convention shown opposite.

CAUTION INFORMATION Do not exceed maximum ratings and ensure sensor(s) are operated in accordance with their requirements. Carefully follow all wiring instructions. Incorrect wiring can cause permanent damage to the device. SST Sensing Ltd recommend using alcohol based cleaning agents. Do NOT use chlorinated solvents such as trichloroethane as these are likely to attack the sensor material. Failure to comply with these instructions may result in product damage.
