Temperature compensation sensor: Operating Voltage 12-24 VDC

Q: Why is temperature compensation necessary in multi-sensor probes?

Temperature variations cause material expansion/contraction and electronic parameter changes that introduce measurement errors. Compensation maintains accuracy across operating conditions.

Q: How often should temperature compensation sensors be calibrated?

Annual calibration is recommended for critical applications, following manufacturer guidelines and ISO 9001 quality system requirements.

Component Specifications

Definition

A precision electronic component integrated into multi-sensor probe heads that continuously monitors ambient or operational temperature and applies real-time correction algorithms to maintain measurement accuracy across temperature fluctuations. It compensates for thermal expansion, material property changes, and electronic drift in sensors like strain gauges, pressure transducers, or displacement sensors.

Working Principle

Utilizes a high-stability temperature sensing element (typically RTD or thermistor) to detect thermal changes. The sensor's output is processed by embedded electronics that apply predetermined compensation coefficients based on material thermal characteristics and sensor calibration data, adjusting the primary sensor readings through mathematical models or lookup tables.

Materials

Stainless steel 316L housing, platinum RTD sensing element, ceramic substrate, gold-plated electrical contacts, silicone encapsulation, nickel-plated brass mounting fittings.
