PRAE Absolute Pressure Transmitter TP12

The PRAE provides a conditioned standard signal: 4–20 mA in two- or three-wire technology, optionally 0–5 V or 0–10 V. Designed for systems and test benches that process the signal without an additional measuring amplifier. The measuring body is a piece of 17-4 PH stainless steel, fully laser-welded and resin-potted. Linearity and hysteresis are ≤ ±0.20 %.

Nominal pressure via selection: relative 100, 250 and 500 mbar as well as 1, 2.5, 5, 10 and 20 bar (zero point at atmospheric pressure), absolute 1, 2.5, 5, 10, 20, 50, 100, 250, 350, 500, 700, 1000, 1500 and 2000 bar (zero point in absolute vacuum). The price depends on the measuring range and sensitivity.
