||Series 2510 Percent Oxygen Transmitter

Series 2510 Percent Oxygen Transmitter


Series 2510 Percent Oxygen Transmitter with a single range of 0-25%. Input power is 24 VDC (supplied by customer). An analog output of 0-10 VDC is provided.

Modifications include the following:

  1. Supply Alpha Omega Instruments’ standard 1/4″ OD quick connect gas fittings.
  2. Machine the same holes normally used to accept Alpha Omega Instruments’ strain relief connectors. In this case, do not supply the connectors, just the machined holes.
  3. Increase the number of internal electrical connections so that negative 24 VDC is accessible from two terminals.
  4. Provide a positive 24 VDC terminal at the end of the terminal strip and label it “P” to be used to power a 24 VDC pump that will be supplied by CVP.

The Series 2510 Percent Oxygen Transmitter is an AC powered (115/230 VAC, 50-60 Hz) 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 2510 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 features 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.
