The transmitter makes highly precise measurements of the slight differential pressure of 100Pa to 20KPa (for example, the difference between atmospheric pressure and room pressure) and then converts them to electric signals (4 to 20mA) for transmission. The superb stability results from a judiciously selected semiconductor pressure sensor that has excellent temperature properties. The sensor can accurately detect differential pressure at the level of several Pa's. The transmitter has a robust aluminum body and compact structure with a built-in sensor and a converter circuit.
This transmitter suits the real-time remote supervision of room pressure.
<Wide pressure range>
Supports a variety of kinds of pressure including coupled pressure (positive and negative), positive pressure and negative pressure.
<Highly accurate pressure conversion of +-2%>
<Incorporated damping function>
The damping function maintains stable output even when measuring pulsating pressure.
<Free mounting direction>
