West Control Solutions TB 45 Temperature Limit Controller

West Control Solutions TB 45 Temperature Limit Controller are used in process control applications where independent limit switching for over or under temperature is required. They allow users to define upper or lower limits by entering setpoint values. If the pre-set temperature limit is exceeded, the output switches to ensure that the system is in a safe state. For example, the limit or monitor device can shut the system down or trigger forced cooling. Applications that often require limit and monitoring devices are ovens, furnaces, combustion plants, steam systems, and food heating equipment, to name a few.

Thermal process applications often require monitors and limiters to be type-tested to appropriate standards, such as EN14597-1, FM3454, and SIL2. West Control Solutions offers a comprehensive range of devices, from simple, cost-effective units to high-end solutions.
