Brand new pressure transducer. Input: -14.5 psi (-1.0 bars) to 30 psi (2.0 bars) Output: 0.5V – 4.5V linear voltage output, see chart below. Works for boost vacuum chamber, 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.
