Acquisition, messaging and regulation of temperatures of solid, liquid and gaseous media in processes and machines via PT100, PT1000, KTY83, KTY84 or NTC sensors.
ABB offers different temperature monitoring relays to meet the needs of yours application.
CM-TCS
The CM-TCS temperature monitoring relays can be used for temperature measurement in solid, liquid or gaseous media. The temperature is acquired by the sensor (PT100) in the medium, evaluated by the device and monitored to determine whether it is between two threshold values (window monitoring) or has exceeded (overtemperature monitoring) or fallen below (undertemperature monitoring) a threshold. As soon as the temperature falls below or exceeds the threshold value the output relays change their positions according to the configured function and the front-face
C512 and C513
The C512 and C513 temperature monitors are display based units for all types of sensors: PT100, PT1000, KTY83, KTY84, NTC-B57227-K333-A1. Depending on the device up to 3 sensors can be connected and different supply voltage versions are available. Basically over- and undertemperatures (window monitoring) can be monitored. For status indication LEDs are included as well as 1 n/o and 2 c/o (SPDT) contact.
Examples of application
- Temperature monitoring in pitch control of a wind turbine
- Motor and system protection
- Controlling and regulation of panel board heating circuits
- Frost monitoring
- Temperature limits for process variables, e.g. in the packing or electroplating industry
- Control of systems and machines like heating, air-conditioning and ventilation systems, solar collectors, heat pumps or hot water supply systems
- Monitoring of servomotors with KTY sensors
- Bearing and gear oil monitoring
- Coolant monitoring
- Monitoring of motors, generators and transformers with build in PT100 sensors
