MD-WYB wireless pressure transmitter

1. Features

★Signal output mode: ZIGBEE wireless communication, comply with the ZIGBEE PRO communication protocol (ZIGBEE 2007 version agreement), communication distance is greater than 150 m ( empty area up to 300 m), instrument shell antenna end compatible with external antenna.

★Adopt intelligent controller with LCD. the base color is blue, can display the pressure current time measurements, pressure unit, data range, battery, etc.

★ With low power consumption mode design, high precision, anti-jamming, free maintenance, meet the requirements of explosion-proof protection grade, parameters can be set, after the blackout, the  data is not lost.

★ There are remote operating functions, which support RTU, computer, intelligent terminal for parameter setting, data reading and so on.

★ It has alarm function.  It alarms when the battery is under voltage, the parameter error, the instrument failure and the pressure overlimit, and the alarm incident is recorded.

★Using nameplate and QR code mark, it is convenient for instrument itself to do the information management.

★It can be used for chemical industry, metallurgy, oil, electricity, water treatment, pharmaceutical, food and other automation industries.
