The HART handheld device is a portable terminal that is used in conjunction with instruments that use the HART communication protocol to set, modify, and display input/output values and self diagnostic results. Set constant current output and zero. And it has HART Moden function, which can be used in conjunction with the upper computer software of various manufacturers to provide more comprehensive adjustment and maintenance of the instrument. Compatible with HART275, HART375, and HART475, it can communicate with almost all domestically produced instruments using the 1151, 3051, and other HART protocols. The communication product categories are as follows: pressure transmitter, differential pressure transmitter, temperature transmitter, electromagnetic flowmeter, vortex flowmeter, target flowmeter, float flowmeter, metal rotor flowmeter, etc. When the system is started or maintained, simply connect the HART communicator to the 4-20mA communication signal line and it can be used!
