The sensor signal of the piezoresistive pressure transmitter is converted into a standard signal output after signal processing circuit. The product has undergone strict screening and performance evaluation through long-term aging and stability assessment processes. Applied to the environment
In relatively harsh outdoor environments, it is required to be able to observe pressure display on site, and to perform zero shift and range adjustment. Suitable for petroleum, chemical, metallurgical, power, light industry, textile, building materials
Process control and pressure measurement in industries such as hydrogeology, food, medicine, and environmental control. It is called a "programmable resistor". Programmable resistor chip enables transmitter to be used with automatic testing equipment
Installation and calibration to improve production quality and reduce costs.
