Products Description
GPT203 IP68 waterproof pressure transmitter，is specially designed for measuring pressure of outdoor or underwater pipeline. Its waterproof grade is IP68, suits for various harsh environment like long-term flooding, immersion, high humidity, and temperature, alternating code and heat, sewage corrosion and others. GPT203 pressure sensor adopts diffused silicon core as the sensitive components, and built-in processing circuit can change the millivolt signal of sensors to standard current and voltage output. It can be directly connected with the computer, control instrument and display instrument, etc. GPT203 pressure sensor, selects high stability and reliability piezoresistive pressure sensor and high-performance dedicated circuit, make it an overall reliable and stable product, and allows long distance signal transmission. The product adopts the design of the input-type outlet method, careful component selection, process verification and curing, cyclic loading stress relief, aging, environmental simulation testing and other processes to ensure the stability and reliability of each product.
