platinum resistance temperature sensor

Platinum resistance temperature sensors have become a staple in environmental and civil engineering monitoring, and for good reason. Their near-linear resistance-to-temperature relationship makes calibration straightforward, while the inherent stability of platinum means the sensor’s drift stays within a few hundredths of a degree per year. Kingmach builds these sensors into rugged housings that survive direct burial, immersion, or mounting inside concrete structures — typical demands in projects like dam safety, tunnel lining, and deep excavation monitoring. Every sensor we provide is matched with a specific calibration certificate, and you can opt for Pt100 or Pt1000 elements depending on your data logger’s input range. For larger installations, we can embed these sensors into multi-point temperature strings, which simplify cable management and data collection across vertical profiles. Since we handle the whole process from element selection to final potting and connector assembly, we’re able to accommodate unusual cable lengths, connector types, or mounting brackets that off-the-shelf products ignore. All sensors are tested against reference standards traceable to national metrology institutes, so you get numbers that hold up during third-party review. Our technical team also helps with matching sensor configuration to your specific readout — whether you’re using a manual readout, an automatic data acquisition system, or a wireless IoT logger. This might mean adjusting the excitation current, wiring layout, or even the sensor’s self-heating coefficient for low thermal conductivity environments. No matter where you’re located, we can deliver quickly through our global distribution network, and our support engineers are available to discuss on-site testing procedures or custom monitoring schemes before you commit.
