Today, I will introduce a national invention authorized patent-a pressure transmitter with isolation membrane. The patent was applied for by Xi'an Senses Sensor Co., Ltd., and the authorization was announced on March 22, 2017.
Content descriptionThe utility model belongs to the field of automatic control, and specifically relates to a pressure transmitter with an isolation membrane.
Background of the inventionAt present, the most commonly used pressure transmitter in the water pump industry is a ceramic pressure sensor, but ceramic pressure transmitters have the following shortcomings: â‘ , slow response; â‘¡, anti-overload difference: the structure of the pressure sensing part of the ceramic pressure transmitter is extremely easy It is ruptured by impact; â‘¢, the accuracy is low; â‘£, the measuring range is small.
Summary of the inventionThe purpose of the utility model is to improve the above-mentioned existing problems in the prior art. That is, the utility model discloses a pressure transmitter with an isolation membrane.
The present invention is a pressure transmitter with an isolating membrane, which includes a connector, a circuit board, a locking ring, a sensor, an O-shaped sealing ring and a base. The O-shaped sealing ring is sleeved in the middle of the outer side wall of the sensor The sensor is fixedly connected to the base through the locking ring, the connector is crimped to the base, and the circuit board is pressed and fixed to each other through the connector and the base, and the sensor A lead wire is provided at one end of the, and the lead wire is connected to the circuit board.
Further, an isolation membrane is provided in the sensor. The central part of the outer side wall of the sensor is provided with an annular groove, and the O-shaped sealing ring is sleeved on the central part of the outer side wall of the sensor through the annular groove.
The pressure transmitter with isolation membrane disclosed by the utility model has the following beneficial effects: correspondingly fast; good overload resistance; high product accuracy; large range, which improves the application range of the product; high safety factor; small size and structure Simple, fast response, sensitive response, anti-corrosion, anti-overload, high precision, and the range coverage is wider than the ceramic pressure sensor commonly used in the water pump industry.
