Product overview
The sensor cleaning and regeneration center is a multi-purpose device for ORBISPHERE sensors.
The product performs these important functions:
• It offers a rapid and efficient method for cleaning sensor electrodes, and in the case of hydrogen
sensors a method of cathode re-chloridization or regeneration.
• It allows a simple check to be made on the circuitry of most sensors to make sure that the sensor
is working correctly, or alternatively trace a fault.
The product consists of two parts:
• The unit itself (Figure
• A regeneration cell with an attached banana plug
The regeneration cell DG33619 is applicable to clean A1100 or C1100 sensors
Note: Two additional banana plugs are supplied to connect to the ohmmeter leads should they need to be adapted
for use with the unit when testing circuits.
Electric power (No. 1 in
for either a 120 V or a 230 V power supply so check to see that the right voltage has been specified
for your needs. Electric power is not needed for the circuit test functions.
The 10-pin LEMO plug cable (No. 3) is used to connect the unit to a sensor for cleaning and circuit
testing. The sensor 10-pin LEMO receptacle (No. 6) fulfills the same function. For sensors with
detachable cables use the unit cable leaving your sensor cable in place and attached to the
