3 Safety
General
This section summarizes the essential precautions applicable to the GPR-2500A Oxygen Transmitter. Additional
precautions specific to individual transmitter are contained in the following sections of this manual. To operate the
transmitter safely and obtain maximum performance follow the basic guidelines outlined in this Owner’s Manual.
Caution: This symbol is used throughout the Owner’s Manual to Caution and alert the user to recommended
safety and/or operating guidelines.
Danger: This symbol is used throughout the Owner’s Manual to identify sources of immediate Danger such as
the presence of hazardous voltages.
Read Instructions: Before operating the transmitter read the instructions.
Retain Instructions: The safety precautions and operating instructions found in the Owner’s Manual should be
retained for future reference.
Heed Warnings: Follow all warnings on the transmitter, accessories (if any) and in this Owner’s Manual.
Follow Instructions: Observe all precautions and operating instructions. Failure to do so may result in personal
injury or damage to the transmitter.
Pressure and Flow
Inlet Pressure: GPR-2500A Oxygen Transmitters are designed for flowing samples, equipped with 1/8” bulkhead
tube fitting connections on the side of the unit (unless otherwise indicated, either fitting can serve as inlet or vent)
and are intended to operate at positive pressure regulated to between 5-30 psig.
Caution: If equipped with a H2S scrubber as part of an optional sample conditioning system, inlet pressure must
not exceed 30 psig.
Outlet Pressure: The sample gas vent pressure should be atmospheric.
Installation
Oxygen Sensor: DO NOT open the sensor. The sensor contains a corrosive liquid electrolyte that could be
harmful if touched or ingested, refer to the Material Safety Data Sheet contained in the Owner’s Manual appendix.
Avoid contact with any liquid or crystal type powder in or around the sensor or sensor housing, as either could be a
form of electrolyte. Leaking sensors should be disposed of in accordance with local regulations.
Mounting: The transmitter is approved for indoor or outdoor use. Mount as recommended by the manufacturer.
Power: Supply power to the transmitter only as rated by the specification or markings on the transmitter
enclosure. The wiring that connects the transmitter to the power source should be installed in accordance with
recognized electrical standards and so they are not pinched particularly near the power source and the point where
they attach to the transmitter. Never yank wiring to remove it from an outlet or from the transmitter.
Operating Temperature: The maximum operating temperature is 45º C.
Heat: Situate and store the transmitter away from sources of heat.
Liquid and Object Entry: The transmitter should not be immersed in any liquid. Care should be taken so that
liquids are not spilled into and objects do not fall into the inside of the transmitter.
Handling: Do not use force when using the switches and knobs. Before moving your transmitter be sure to
disconnect the wiring/power cord and any cables connected to the output terminals located on the transmitter.
