Transducer

The original YF1512 failed testing so this is the replacement from http://www.ebay.com/usr/renbusan?_trksid=p2047675.l2559

• A: GND
• B: V+
• C: Vout

It came with a short cable but the wire was too thick so a new harness was made. A 4 position Molex C-Grid is on the other end.

• 1: Vout (White)
• 2: V+ (Red)
• 3: nc
• 4: GND (Black)

Looks like a Honeywell PX2 or PX3 part, except Honeywell doesn't seem to offer a 5 psi version. The connector is a three contact Delphi Metri-Pack 150. With IP67 it is probably Absolute reading.

Input: 0-5 psi. Output: 0.5V – 4.5V linear voltage output.0 psi outputs 0.5V, 2.5 psi outputs 2.5V, 5 psi outputs 4.5V. Works for oil, fuel, water or air pressure. Can be used in oil tank, gas tank, etc. Accuracy: within 1.5% of reading (full scale). Current draw: less than 4 mA. Burst (over or max pressure) pressure: minimum 100 psi. Thread: 1/8”-27 NPT. (see our fitting set for other thread size below). Wiring connector: water sealed quick disconnect. Mating connector and wire harness (pigtail) is included. Wiring: Red for +5V. Black for ground. Blue for signal output. Our material is using top of line 316 stainless steel (not 304) and high temperature auto-graded plastic. This is a high quality pressure sender, with ceramic pressure chip sensor inside.
