Instrument Overview
By adding the YGQT series transmitter display kit, the transmitter can have a display function to meet customer on-site display needs. Universal 33mm mounting hole distance, compatible with E+H, Rosemount, Siemens, ABB, and other domestic and foreign manufacturers' temperature transmitter modules.
Typically used in combination with 2-wire temperature transmitter modules, it is loop-powered, requiring no external power source. It can be matched with various transmitters for temperature, pressure, flow, and level, and is suitable for transmitters requiring local indication or for use in low-temperature applications. The product features a circuit designed for immunity to Electrical Fast Transients (EFT/Burst) and Radio Frequency (RF) electromagnetic fields. It achieves Level 4 immunity for EFT/Burst and radiated RF field immunity of >10V/m (80 MHz to 1000 MHz). This product effectively protects against damage caused by line faults, switching operations, operating frequency converters, and on-site electric welders during construction.
