RS232 To RS485 Converter

Ztech’s digit RS232 to RS485 converter is designed to offer a truly simple, cost effective digital pressure gauge to cover a wide range of applications from calibration laboratory to in-field use. It indicates pressure with different selectable units by user with the resolution of maximum 6 digits in battery operated version. It has auto power OFF function in battery operated model. It has other model in which it can be used as loop power indicator with 4- 20mAdc transmitter by giving 15 to 24Vdc external supply voltage. In this version it will give you resolution of four digits with selectable multiplying factor for different unit scales with red LED display.
It is operated by high precision piezoresistive silicon sensor technology. It is available in two different applications for air, gases (dry) media other model is for air & liquid with SS316 diaphragm.
