Good Practice Guide: Control Sensor Selection and Installation

A Building Energy Management System (BEMS) is only as good as the sensor used to measure the controlled variable (temperature, humidity, pressure etc.) and transmit it as a measured value to the controller. It is crucial that the sensor should provide an accurate measurement of the controlled variable at the reference point in the control loop.

Good Practice Guide Control Sensor Selection and Installation A Building Energy Management System (BEMS) is only as good as the sensor used to measure the controlled variable (temperature, humidity, pressure etc.) and transmit it as a measured value to the controller. It is crucial that the sensor should provide an accurate measurement of the controlled variable at the reference point in the control loop. Failure to meet the desired conditions satisfactorily, can lead to poor control, energy wastage and occupant complaints. Traditional BEMS uses hard wiring between sensors and controllers. Later technologies such as wireless, internet based and SMART sensing technologies are also available and are outside the scope of this document. This document sets out to describe good selection and installation of HV/AC sensors used in BEMS.
