The current is measured and processed by the PGU-P sensor, generating the signals that are passed to the SSS-903 receiver via RS-485. Each detector is factor programmed for the gas requested by the customer at the time of purchase.

PGU-E Electrochemical Gas Sensor Theory of Operation Figure6 – TG-E Detector The PGU-P sensor contains electrode in contact with an electrolyte. The target gas diffuses into the sensor through a membrane and comes into contact with electrodes where it is oxidized. The electrochemical reaction results in an electric current that passes to PGE-P microcontroller and from there to the SSS-903 receiver.

The detector module may be replaced in the field with a one that is intended for use to detect the same gas. If a different gas is required a replacement PGU module must be ordered from ESP Safety or their representative. Aside from detector or filter replacement there are no user serviceable parts in the PGU sensor.
ESP-Commander may require a customer provided translation device. All ESP Safety gas detector models have the ability to interface with ESP Commander in RS-485 “daisy chain” networked installations. Modbus is also available in a single point to point interface (one SSS-903 to One port of a control system as a data signal that is imbedded in the +4 to 20mA analog output.
Be sure to read and understand the entire instruction manual before installing or operating the gas detection system. The products described in this document can be used with a variety of ESP-Safety gas detector models to provide earlywarning of the presence of a toxic or explosive gas mixture.
Personnel exposure sensor location should include the potential leak source and perimeter of personnel. Use of ESP Safety PGUAES open field detectors should be considered for these areas. Consideration should be given to providing easy access for maintenance personnel. Maintenance Access PGU sensor location should also take into account the proximity to contaminants that may foul the PGU sensor prematurely.
