NODING变送器P131系列介绍
P131压力变送器具有大型过程连接和前置齐平测量传感器。可以最有效地防止膜堵塞，并且可以在必要时轻松清洁。该传感器经过 ATEX 和 DNV-GL 认证，还可用于潜在爆炸区域，并具有出色的机械强度。陶瓷传感器元件可抵抗侵蚀性和磨蚀性介质。即使在最低压力和高过载电阻下，电容测量原理也能实现非常准确和长期稳定的测量。过程连接由不锈钢 1.4404 或 PVDF 等优质材料制成，因此适用于几乎所有介质。

模拟输出：
4…20 mA，2 线
0…10 V，3 线
The P131 pressure transmitter features large process connections and a front-flush measuring sensor. Clogging of the membrane is prevented most effectively and can be easily cleaned if necessary. ATEX and DNV-GL certified, the sensor can also be used in potentially explosive areas and features excellent mechanical strength. The ceramic sensor element is resistant to aggressive and abrasive media. The capacitive measuring principle enables a very accurate and long term stable measurement, even at lowest pressures and high overload resistance. The process connection is made of high-quality materials such as stainless steel 1.4404 or PVDF and is therefore suitable for almost all media.
