ENMET Corporation P/N 10022-0803, SDS-97D Series Sensor/Transmitter Ozone, O3 P/N 10022-0803

P/N 10022-0803, SDS-97D Series Sensor/Transmitter Ozone, O3 SDS-97D Series Sensor/Transmitters utilize electrochemical type cells to detect the target gas. These cells consist of electrodes, electrolyte and an air/liquid separation barrier. Gas molecules enter the cell and, as a result of an oxidation/reduction reaction, generate an electrical current proportional to the gas concentration. This current is measured, conditioned, converted to the gas concentration, digitally displayed and transmitted as a 4-20 mA output signal. ENMET offers a variety of multi-channel controller/alarm modules that provide the 24 VDC power and receive the 4-20 mA signal from the sensor/transmitters. These sensor/transmitters can also be connected to various computer based instrumentation, PLCs, etc. The use of a gas sampler generally improves monitoring performance for all gases. It is particularly recommended for Cl2, HCl, AsH3, and it is required for monitoring HF and O3. The standard SDS-97D Sensor/Transmitters (P/N 10022-XXXX) incorporate an external push button for non-intrusive zeroing and gas calibration of the device. An optional version of the SDS-97D Sensor/Transmitters (P/N 10021-XXXX) feature a communication port and hand-held programming module (P/N 10021-001) which facilitate the elimination of the need for on-site gas calibration.
