The Series 2500 Trace Oxygen Transmitter is a true loop powered (14-32 VDC) percent oxygen transmitter designed to provide accurate and dependable percent oxygen measurements in a variety of background gases. Measurement ranges available are from 0-2% to 0-100%. The Series 2500 enclosure is made from durable polycarbonate and is rated for NEMA 4 (IP 66) service (may change with the addition of certain optional equipment). A 4-20 mADC output is provided that can be used with a data logger, recorder, PLC, DCS, etc. Options include pressure regulators, flow meters, sample filters, and explosion proof (NEMA 7) housings.
The Series 2510 Percent Oxygen Transmitter is the AC powered (115/230 VAC, 50-60 Hz) counterpart to the Series 2500 and is recommended when AC power is available or preferred. Also, available in optional 24VCD. : In addition to the optional equipment mentioned above, the Series 2510 can be equipped with sample pumps and flowmeters.
The Series 2500 and Series 2510 Percent Oxygen Transmitters feature an extended life oxygen sensor with EES (enhanced electrolyte system). This sensor provides exceptional performance, accuracy, and stability. For applications where carbon dioxide is present in the sample gas, the EES retards passivation of the sensor anode by allowing the products of oxidation to dissolve in the electrolyte. In effect, the sensor is renewed continuously, resulting in an increase in sensor life even if exposed to 100% carbon dioxide. In addition, the enhanced mechanical design of the sensor ensures longer life, and virtually eliminates leakage of electrolyte, a nagging (and expensive) problem associated with sensors that require periodic electrolyte maintenance.
