Wireless sensor transmitter with indicator light TX 4/20 600-035

for sensorsLEDhigh-precision

Overview
The 4/20mA LoRaWAN sensor is designed to be connected to a 4/20mA probe. It measures the probe's 4/20mA signal and transmits the measured data over LoRa radio. This enables a variety of applications (for example: pressure measurement, radon monitoring, measurement in extreme temperatures).

Main features

• Connection of a 4/20mA probe via terminal block.
• Measurement of the 4/20mA signal with 12-bit resolution.
• LoRa radio transmission (long range, > 5 km in open field).
• Communication modes: LoRaWAN (public or private network) and LoRa Easy (dedicated communication to LoRa Easy receiver).
• Integration compatibility: native decoding and mapping of data to Modbus registers or BACnet objects for BMS integration; possibility to send JSON to an HTTP server via LoRa Easy receiver.
• Sensor power: replaceable D-type 3.6 V lithium battery (replacement battery supplied).
• Battery life: up to 15 years (depends on transmission settings and environment).
• Diagnostic indicators: 3 LEDs.

Operating modes

• LoRaWAN mode: transmission over a public or private LoRaWAN network. Compatible with LoRaWAN gateways on the market.
• LoRa Easy mode: transmission to LoRa Easy Enless receiver (receivers available in Modbus, BACnet and HTTP versions). LoRa Easy receivers enable reception and conversion of data for straightforward integration.
