SKU#
WS433-MA
Replaced by
Replaced SKU
Wireless sensor with one channel to measure 0-20mA DC current from Process instruments like Pressure transmitter, Temperature transmitter, Level transmitter, Flow meters, Analyzers... at very low voltage drop. It is configured the operation parameters like data sending interval, health check cycle... remotely from Globiots platform or via ModbusRTU software. The wireless module can last up to 10 years with a single AA battery.
For Applications
Process Monitoring, Safety Monitoring
Reliable & Secured Wireless Connection
Sub-Ghz technology from Texas Instruments allows reliable wireless connection and secured data by AES-128
Low Voltage Drop
Only 3.0VDC voltage drop on the current loop
10-year with a single battery
Ultra-low power sensing technology from Daviteq with Ultra-low power wireless technology fromTexas Instruments allow the sensor can last up to 10 years with a single battery AA.
