BMS Field Sensor (Temperature / Pressure / CO₂) Maintenance Checklist
Keep control decisions based on real values — calibration and drift checks on temperature, pressure, humidity, and CO₂ sensors, plus siting and wiring verification.
What is a bms sensor maintenance checklist?
A bms field sensor (temperature / pressure / co₂) maintenance checklist is a structured list of the 10 preventive maintenance tasks — covering visual, functional and record-keeping checks — that keep a bms field sensor (temperature / pressure / co₂) running safely and reliably. It groups routine checks by frequency, from daily inspections to annual servicing, so FM teams and building engineers can plan and evidence preventive maintenance.
Core bms sensor checks
- Check temperature sensors are well sited
- Compare each sensor reading against a calibrated reference instrument
- Record readings, references, calibration, and replacements in the log
What is a bms field sensor (temperature / pressure / co₂)?
BMS field sensors measure the conditions the control system acts on — air and water temperatures, pressures, humidity, CO₂, and valve or damper positions. Every control decision is only as good as the sensor feeding it: a sensor reading 2°C high will make the BMS overcool a space and waste energy indefinitely, with no fault ever shown. Sensors drift, get poorly sited, or fail open/short. Maintenance verifies readings against calibrated instruments, checks siting and exposure, and confirms wiring and signal integrity, so the control strategy and the energy data it produces can be trusted.
Typical BMS Sensor maintenance checklist
A practical starting point for planned preventive maintenance. Always refer to the manufacturer's O&M manual and site-specific requirements.
Visual Checks
- Check temperature sensors are well sited — not in draughts, sun, or dead air
- Inspect sensor wiring, terminations, and screening for integrity
- Check averaging/duct sensors are fully and correctly installed
Functional Checks
- Compare each sensor reading against a calibrated reference instrument
- Verify pressure/DP sensors read correctly and tappings are clear
- Confirm CO₂ and humidity sensors are within calibration and not contaminated
- Check valve/damper position feedback matches the actual position
- Recalibrate or replace sensors reading outside acceptable tolerance
- Confirm immersion sensors have pockets filled with conductive paste/oil
Record Keeping
- Record readings, references, calibration, and replacements in the log
Typical maintenance frequency
Suggested intervals for bms field sensor (temperature / pressure / co₂) maintenance. Actual frequencies should follow manufacturer guidance and site-specific risk assessments.
Quarterly
- •Spot-check key sensors against a reference
- •Inspect siting and wiring
- •Check position feedback
Annually
- •Full calibration check of control sensors
- •Recalibrate/replace drifted sensors
- •Verify CO₂/humidity sensors
- •Update calibration records
