Product Description

 

Product Description

Product Overview
PC10PTFE, PTFE type silicon piezoresistive pressure sensor is the core component of pressure sensor and pressure transmitter as the high performance pressure sensitive element. It adopts integrated structure, high static pressure resistance, stable and reliable.
PC10PTFE sensor is a diffused silicon pressure sensitive chip encapsulated in a 316L stainless steel housing. The external pressure is transmitted to the sensitive chip through the stainless steel diaphragm coated with PTFE and the internally sealed silicone oil. The sensitive chip does not directly contact the measured medium, forming a fully solid-state structure for pressure measurement. Therefore, this product can be used in various occasions, including harsh corrosive media environments.
PC10PTFE sensor uses an O-ring for pressure sealing, which is easy to install.
Our company can also undertake special customization according to user needs, such as fully welded structure, wide temperature compensation, high reliability, strong impact resistance and vibration resistance pressure sensors, especially for national defense weapons and equipment.

Ordering tips:
1 Pressure range can be selected higher or lower than actual conditions but should be within ±30%FS.
2  Pressure reference consists of gauge pressure, absolute pressure and sealed gauge pressure.
Gauge pressure is based on the current atmospheric pressure. Generally, it refers to the measurement of pressure which is greater than the current atmospheric pressure. Negative pressure is a special case of gauge pressure. It refers that there is such working condition that the pressure of work site is lower than the current atmospheric pressure.
Absolute pressure is based on vacuum.
The sealing pressure is the absolute pressure used as the gauge pressure, but the reference is the atmospheric pressure at the production site. There is no gauge pressure above 4MPa, only sealing pressure.
3 Confirm the maximum overload of the applied system, which should be less than the overload protection limit of the sensor, otherwise it will affect the product life or even damage the product.
4 The commonly used compensation of the product is 1.5mA constant current compensation. Suggest to
select the option with priority.
5 The material and process for manufacturing negative pressure sensors are different from those of positive pressure sensors. So gauge pressure sensors cannot be used as substitute of negative pressure sensors.
