Ap304/5 Sensors - ABB AP300 User Manual

2.1.3 AP304/5 Sensors

Warning.
— To avoid operator injury if the probe ejects to its end
stop, keep a safe distance when releasing the
compression fitting.
— Undo the compression fitting slowly as the probe can
slide out to its end stop under process pressure.
— It is hard to insert the probe above a process pressure
of 80 psi.
— Process pressure must not exceed 6 bar (87 lb in
25 °C (77 °F) continuous. Retract sensors during
process start-up to prevent damage due to pressure
surges or water hammer.
— Insert the sensor only as far as necessary to achieve
representative flow. Over-insertion may damage the
sensor and/or cause slow response.
— Fully retract the sensor before closing the valve and
fully open the valve before inserting the sensor.
