Frequently Asked Questions About Wireless Temperature Sensors

The Leap transceiver node can support multiple temperature sensors of different types including:

  • 2-wire and 3-wire PT100s and  PT1000s.
  • Thermocouples of every type.
  • Digital temperature sensors
  • Thermistors (less common)

The wires to the temperature sensor can be integrated with an IP67 M8 connector or the cable can be run through a metal IP67 cable gland and attached to the spring-loaded terminal block inside the enclosure.

Yes.  We can verify them against a NIST traceable temperature standard and supply a certificate of conformance to that NIST traceable standard.

Common Applications for Wireless Temperature Sensors

  • Manufacturing & Process Control: Temperature sensors for industrial applications track process temperatures at multiple points such as ovens, mixing tanks, curing stations. Wireless temperature transmitters avoid the wiring complexity of moving parts or rotating equipment.

  • Food & Beverage Production: Wireless temperature monitoring systems support the documentation many facilities are required to maintain for regulatory or safety compliance, without requiring error-prone manual readings.

  • Pharmaceutical Manufacturing: Precise remote temperature monitoring to support process control and regulatory documentation in pharmaceutical environments, where temperature excursions can affect product quality or safety.

  • Hard-to-Reach or Remote Locations: Wireless temperature sensors are well suited to chimneys, rotary ovens, furnaces, and other locations where running cable is impractical, extending remote temperature monitoring to equipment that would otherwise go unmonitored.

  • HVAC & Building Systems: Industrial temperature sensors installed across HVAC equipment support a broader temperature monitoring system. Track supply/return air temperatures, detect equipment failure, and protect plumbing from freeze damage in unoccupied or seasonal spaces.

  • Warehousing & Distribution: Deploy remote temperature monitoring system across warehouse space to track ambient conditions for temperature-sensitive inventory.

What Sets Leap Wireless Temperature Sensors Apart

Beyond wireless transmission, the system is built to support the full range of industrial temperature sensors, suited to different applications and accuracy needs.

RTD & PRT Temperature Sensors

For high-accuracy measurement, the Leap transceiver node integrates with standard industrial RTD probes or higher-accuracy PRTs, including off-the-shelf PT100 probes. A three-wire connection factors out changes in cable resistance caused by temperature swings, so the measurement reflects the probe tip alone rather than the cable run for precise industrial temperature sensor applications.

Digital Temperature Probes

Digital temperature sensors are well suited to non-extreme temperature ranges and offer a replaceable, calibrated probe tip which is often required in applications like vaccine and cold-chain monitoring. Because the tip can be swapped annually for a newly calibrated one, facilities can maintain calibration compliance without replacing the full sensor, keeping the temperature monitoring system cost-effective over time.

Thermocouple Sensors

Thermocouples support a wide temperature range and are common across many industrial temperature sensors for industrial applications. The Leap transceiver node uses a standard mini blade thermocouple connector for quick setup with off-the-shelf probes (K-type standard, with J, T, N, S, E, B, and R types also supported.) There is also an option to connect directly to a terminal block using screw terminals. Built-in cold junction compensation and electrical isolation on each thermocouple circuit help eliminate ground loop measurement errors when two grounded thermocouples are used.

Wireless Connectivity & Data Management

Each transceiver node transmits temperature data with a unique ID to the gateway, with a status LED indicating wireless connection status. Two-way communication lets the gateway push configuration and firmware updates to sensor nodes remotely.
