PBTC-200 and PBTC-300 are electronic thermostat modules in an Ex e certified polyester junction box.
The thermostat modules have been developed as on-off temperature controllers for trace heating applications.
The adjustable temperature setpoint allows flexible applications in the range of frost protection and temperature maintenance of liquid or gaseous media on pipes or tanks.
The integrated LED status display indicates the current operating status of the unit or system by means of colour and flashing codes; the temperature unit can be switched between °C and °F.
Approvals for the direct connection of BARTEC self-limiting heating cables are available.
