Overview
The VFG54+ measures the temperature of cold or hot water on pipes and other curved surfaces. A spring loaded brass contact sensor gives a quick response, and a hinged cover with tool-free terminals speeds up wiring. The MultiRange models output 0 to 10 V (TRV) or 4 to 20 mA (TRA) over a selectable temperature range, up to -50 to +250 °C scaling. Relay versions add two floating contacts for a two-stage thermostat, and LCD versions add a colour changing display with a traffic light function.
