Glass Micro Melt Sensor PC10R

Product overview

The PC10R micro melt sensor is the core component for manufacturing pressure sensors and pressure transmitters. As a high-performance and impact resistant pressure sensitive element, it can be easily amplified and assembled into a standard signal output transmitter.

For the micro melt sensor, a sensitive chip is bonded to a 17-4PH stainless steel diaphragm through glass adhesive, and external pressure is transmitted to the sensitive chip through the stainless steel diaphragm. The sensitive chip does not directly contact the measured medium, forming an all solid structure for pressure measurement.Therefore, this product can be applied in various occasions,especially in environments with high impact and harsh corrosive media.

The micro melt sensor is pressure sealed with an O-ring for easy installation.

The company can also undertake special customization according to user needs, such as pressure sensors with fully welded structure, wide temperature compensation, high reliability, strong impact resistance, and vibration resistance, especially for supporting national defense weapons and equipment.
