PMA TB 45 Temperature Limiter
The TB 45 temperature limiter is intended for precise, cost-effective signal monitoring & limiting tasks.
The TB 45 can be used for heating and refrigeration processes. It is suitable for all thermocouple types and resistance type sensors. It is particularly designed for use in: all applications where an over or under temperature fault condition could present fire hazard or other hazard, heating system in buildings to DIN EN 12828, large hot-water boilers to DIN EN 12953-6, thermal transfer plants with organic heat transfer media to DIN 4754, oil-fired installations to DIN 4755 and limit signalling function for any type of input signal.
