C-IT-0100H-P

The C-IT-0100H-P module is a temperature sensor in a plastic head, which can be connected directly to the CIB bus. The module contains two measurement inputs. One input (the master) is permanently connected to the resistance temperature sensor in the stem (Pt1000), which is used for primary temperature measurement. The second input is connected to the resistance sensor that measures the temperature inside the head and is used for information about the operating conditions of the module. The resistance is converted in the module directly into the temperature numerical value and transmitted to the central unit over the CIB bus. The software - firmware - is optimized to increase the accuracy and linearization of the measuring range of the sensor directly in the unit. The processing principle eliminates distortion or possible measurement errors, when the external sensor is connected over a long distance.

The module is supplied in several versions: a sensor inside the piping, a sensor with a stem, an outdoor sensor and a contact temperature sensor. For details of the options, including the mechanical dimensions, see the Chapter Measuring temperature.

Notes:

1. Connecting the wires in the bus is done using a gland in the terminal block, which is accessible after the cap is taken off the head.

2. The cap is secured with four bayonet screws (they can be released by turning anti-clockwise).
