Raychem RAYSTAT-EX-03 Hazardous Area Electronic Thermostat
SURFACE AND AMBIENT SENSING, ELECTRONIC
These electronic surface sensing and ambient thermostats provide accurate temperature control for heating cables.
The units can be supplied at nominal voltages of either 110 V 50/60 Hz or 230 V 50/60 Hz and have a double pole switch rated at 16 A.
The switch contacts can be arranged to be volt free.
Temperature setting is accurate via digital thumb wheel switches inside the enclosure.
The surface sensing version is supplied with a Pt 100 sensor and a 2 m long stainless steel sheathed extension cable giving freedom to locate the electronics remote from the sensor.
The ambient version is supplied with a local Pt 100 sensor and a wind shield.
The enclosure is manufactured from high impact resistant glass filled polyester offering IP66 protection. For pipe temperatures up to 215°C, the units can be mounted on the pipe using a support bracket.
