Series 2500/2510 Percent Oxygen Transmitters Explosion Proof

Series 2500/2510 Percent Oxygen Transmitters (Explosion Proof)

Percent Oxygen Measurement

 

The Series 2500 and 2510 Percent Oxygen Transmitters are blind transmitters designed to provide exceptional performance, accuracy, and stability. Percent oxygen measurement ranges are available from 0-2% to 0-100%.

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). Available in an optional NEMA 7 (explosion proof) enclosure.

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, and sample filters.  In addition to the optional equipment mentioned above, the Series 2510 can be equipped with sample pumps and flowmeters. A 4-20 mADC analog output is provided.

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.

Features

A factory Certificate of Performance Verification and Calibration is included at no additional charge. The product performance is verified in accordance with manufacturing specifications using a National Institute of Standards and Technology (NIST) traceable transfer calibrated standard gas mix.
