WatchGas 15J(win) / 30J(win) — Gas Transmitter
The rugged, weatherproof WatchGas 15J(win)/30J(win) gas transmitter is designed for permanent installation, including mounting on car park columns. The 30J housing opens with two Allen screws, simplifying service and calibration. 4-20 mA (3-wire) or CANbus (4-wire, addressable) output, with optional alarm relays.
Key features
- Rugged, weatherproof housing — fast service access via two Allen screws (30J version).
- 4 spacer mounting brackets improving air circulation and response time, and simplifying installation on round columns (e.g. in car parks).
- Standard 4-20 mA output with CANbus addressing — operation on a network with a WatchGas Combi control panel or another monitoring system.
- Available in addressable or stand-alone versions.
- Hyper Terminal (RS232) communication for configuration and data readout via a 232 adapter.
- Event logger (addressable versions) — intervals from 1 minute to 1 hour, memory for 2,880 readings.
