Product Overview:

PM400 is an analog capacitive thin film vacuum transmitter with high measurement accuracy, good long-term stability, and is not limited by gas types. Its corrosion-resistant ceramic force sensor is temperature compensated, with a wide operating temperature range and good zero stability.

The overall size of the transmitter is compact, simple and reliable, suitable for precise measurement of complex gas components in medium and low vacuum. The output voltage range of the transmitter is 0~10V, and there is a linear correspondence between voltage and vacuum degree; The electrical interface is RJ45 (FCC68), which can replace capacitor film vacuum gauges from brands such as Yingfukang and Laibao.
