Veris Industries TOKR00 Sensor

The Veris Industries TOKR00 Sensor is a precision outside air temperature sensor designed for accurate environmental monitoring in building automation systems. Engineered for durability in demanding exterior conditions, this 10k ohm thermistor features a built-in 11k ohm shunt to ensure signal stability and compatibility with a wide range of HVAC controllers and resistive inputs. The TOKR00 is a direct replacement for Barber Colman TS-5751-850, making it a reliable solution for maintaining legacy systems or integrating into new commercial outdoor reference air applications.

Constructed with a robust ABS plastic enclosure and rated for IP65 (NEMA 4) protection, the TOKR00 is built to withstand moisture and debris. The sensor probe is integrated within a radiation shield, a critical design feature that mitigates solar heating effects and prevents "heat soak" errors that lead to inflated temperature readings. With an operating temperature range of -13 to 221 °F (-25 to 105 °C), this weather-resistant junction box provides a stable resistive output for economizer control, discharge air monitoring, and general building management troubleshooting.

• High Accuracy Sensing: Delivers precise 10k Type 2/3 thermistor performance with a 11k shunt for reliable controller feedback.
• NEMA 4 Protection: The IP65 rated weather-resistant housing ensures long-term operation in rain, snow, and high-humidity environments.
• Integrated Radiation Shield: Specifically designed to reduce the impact of direct sunlight on the sensing element for true ambient readings.
• Direct Compatibility: Functions as a seamless replacement for obsolete Barber Colman / Schneider Electric outdoor sensors.
• Simplified Installation: Features 22 AWG pigtail terminations for rapid field wiring into standard 1/2 inch conduit or direct wall mounting.

Common Questions:

How do I verify the accuracy of the TOKR00 during inspection?
Use a calibrated multimeter to measure the resistance at the pigtails and compare the reading to a standard 10k thermistor curve with 11k shunt offset. For precise measurement, ensure the probe is dry and shaded during the test.

Where is the best location to mount this outdoor air sensor?
Technicians should mount the sensor on the north-facing side of the building, away from exhaust vents, air outlets, or windows that could provide false heat readings, typically at least 15 feet above the ground.

Can this sensor be used with 24VAC power systems?
This is a resistive output sensor (passive thermistor). When wiring to controllers using 24VAC, ensure you are landing on the correct resistive input terminals to avoid induced voltage issues.
