The HPM713 ceramic diaphragm pressure transmitter utilizes an advanced ceramic piezoresistive core as its sensitive element and features a threaded installation with a flat diaphragm design. Ceramics exhibit exceptional properties including high elasticity, wear resistance, corrosion resistance, and rapid heat dissipation. These characteristics contribute to the transmitter's outstanding thermal stability, enabling reliable operation in temperatures ranging from -40 to 120 degrees Celsius with minimal temperature drift.

Due to the absence of filling liquid in the ceramic sensor, it eliminates the risk of process pollution. The dry ceramic diaphragm remains unaffected by the installation direction. The exposed diaphragm on the product's end face directly senses the pressure, effectively eliminating issues such as scaling, unsanitary conditions, and viscous pressure blockage. As a result, this transmitter finds wide application in measuring media containing particle impurities, as well as in pressure measurement scenarios susceptible to blockage or scaling.

Additionally, the HPM713 transmitter proves valuable in hygienic industries such as food, medicine, and winemaking. Its reliable performance and resistance to process contamination make it an ideal choice in these sectors.

Overall, the HPM713 ceramic diaphragm pressure transmitter offers superior functionality and versatility, making it suitable for a wide range of demanding applications.
