Honeywell – External Probe for Freezer and Refrigeration Monitoring, T280R – USA

The Honeywell T280R is a temperature probe intended for use with Honeywell 5821, T280 or TS300 sensors. The T280ZR probe is used to detect temperatures remotely from its main temperture sensor. The T280R features a resistance value of the probe at both extremes: -55C: 9,637,300 ohms. +25°C: 100,000 ohms. +50°C: 36,024 ohms. +150°C: 1,861 ohms. Accuracy: 0.2° C or 32.36°F. To mount the T280R or TS300R, it can be extended for 15′ up to 300′ max. using shielded 24AWG or larger cable. Insure shield is grounded for noise immunity. Any other gauge wire at any distance longer than specified can cause unpredictable results. The only difference between the TS300R and T280R is that the TS300R comes with a mounting strap and screw to secure the probe in place and T280R does not.
