Differential pressure transmitter [PLT]
Differential pressure transmitter [PLT series]
This transmitter makes highly precise measurements of fine differential pressure of 100 Pa to 20 KPa (for example, the difference between atmospheric pressure and room pressure) and then converts them to current signals (4 to 20 mA) for transmission.
A carefully-selected semiconductor pressure sensor with excellent temperature characteristics is used for the sensor for excellent stability.
The sensor can accurately detect differential pressure at the level of a few Pa.
The transmitter has a robust aluminum body and compact structure with built-in sensor and converter circuit.
This transmitter is ideal for real-time remote supervision of room pressure.
Features
＜Wide pressure range＞
Supports a variety of kinds of pressure including compound 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＞
