Monitors & limiters

Exhaust gas temperature monitor

The exhaust gas temperature monitor is used to monitor the exhaust gas temperature released from solid fuel boilers when in bivalent operation with oil-fired boilers. Another application is the locking of ventilation systems that cause vacuums in combination with tiled stoves and chimneys.

Hot air thermostats

The thermostats of the WTHc series are suitable for use in hot air systems according to DIN 4794 and consist of 3 separate measuring and switching systems with the following functions: temperature controller (TR), temperature monitor (TW), and safety temperature limiter (STB).

JUMO exTHERM S200

The surface-mounted thermostat is available as a single or double thermostat with capillary or rigid thermowell. A microswitch is used as the electrical switching element. The device operates according to the principle of liquid expansion. It is available as a temperature monitor, safety temperature monitor, and safety temperature limiter. Additional thermowells allow use in zone 0.

JUMO exTHERM-AT

The product monitors and controls temperature in potentially explosive areas. Use in environments with gas and steam is permitted (zones 1 and 2); use in environments with conductive dust (zones 21 and 22) is also permitted.

JUMO frostTHERM-AT/-DR

The product monitors the temperature in ventilation and air-conditioning systems. It has a small switching differential and a high level of reproducibility. The AT version allows mounting on the wall; the DR version is suitable for DIN-rail mounting.

JUMO frostTHERM-ATE

The frost protection thermostat is used on the air part of air-conditioning systems, heat exchangers, heating registers, and similar units to protect them against frost damage and freezing. Applications include in building automation and the ventilation and air-conditioning industry.

JUMO heatTHERM

The product is available as temperature controller (TR), temperature monitor (TW) (type 602030), safety temperature monitor (STW), or as a safety temperature limiter (STB) (type 602031). The panel-mounted thermostat is RoHS-compliant and cadmium-free.

JUMO heatTHERM P300

The 3-phase JUMO heatTHERM P300 can switch outputs up to 480 V at 30 A. All phases are disconnected from the power grid simultaneously here. The device is a safety temperature limiter (STB) and sets the system being monitored to a safe operating status in the event of a malfunction.

JUMO heatTHERM-AT and DR

The JUMO heatTHERM-DR (design type 7+8) type is a specific variation with a special case bottom section for DIN rail or wall mounting. As a result, easy installation on mounting rails TH35 according to DIN EN 60715 (e.g. in control cabinets) is possible.

JUMO safetyM STB/STW

The device is primarily built to monitor thermotechnical processes accurately and switch the systems to a safe operating status in the event of malfunctions. As a result, risks to people, the environment, production facilities, and production goods can be identified and averted at an early stage.

JUMO safetyM STB/STW Ex

The compact and user configurable JUMO safetyM STB/STW Ex can enable early and reliable detection of risks in Ex areas which could potentially result in personal injuries, environmental damage, or destruction of the production facilities and production goods.

JUMO safetyM TB/TW

The JUMO safetyM TB/TW is a user programmable limiter/monitor. The universal measurement input is user configurable for RTD temperature probes, thermocouples, and current or voltage signals. TB/TWs are used to monitor thermal processes in plants for a set limit value.
