XH pressure transmitter for use
1 Overview
Pressure transmitter using piezoresistive pressure-sensitive core body core, application specific integrated circuit inside the sensor millivolt signal into a standard voltage, current or frequency signals, and computer interface card can directly control the instrument, intelligent instrument, or other easily connected to the PLC . Current output can be used long-distance transmission mode. Small size, light weight, stainless steel seal structure can be corrosive environments. The product is simple and easy to install, has a very high shock and impact resistance, widely used in process control, aviation, aerospace, automotive, medical equipment, HVAC and other fields. Overload of 200%.
