This gauge-type transducer measures pressure relative to atmospheric (not absolute), and has a vent tube in the connecting cable to maintain that reference — keep the vent tube end dry and unkinked or readings will drift. At this pressure range, a PT-SNUB-01 pressure snubber is strongly recommended to protect the transducer from hydraulic spikes and surges.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eUse\u003c\/strong\u003e\u003cbr\u003eThread into any 1\/4\" NPT female fitting. Install torque 133-177 in-lbs (15-20 Nm). Install a PT-SNUB-01 pressure snubber first if monitoring a spike-prone system such as hydraulics, then thread the transducer into the snubber's outlet. Connect the white wire to the positive (+) terminal and the brown wire to the negative (-) terminal of a free FPM100 channel.
