Honeywell thin film platinum resistance temperature sensors are precise, interchangeable temperature sensors with excellent stability, small mounting dimensions, and can be directly mounted on printed circuit boards.
The HEL-776 and HEL-777 are thin‑film RTD temperature sensors with a resistance of 1000 Ω at 0 °C. They are designed for compact mounting on printed circuit boards and are available in SIP and surface‑mount packages. The sensors offer high stability, low drift, and a linear resistance‑temperature relationship.
Key performance data include a temperature range of –55 °C to +150 °C, accuracy of ±0.5 °C (or 0.89 % of reading), a time constant of 16 s in air, and a stability of 0.1 % from –40 °C to 125 °C. The manual also provides mounting dimensions and material information for proper installation. This manual is written in Chinese.
| Sensor type | RTD (PT1000) |
|---|---|
| Temperature range | -55 °C to +150 °C |
| Accuracy | ±0.5 °C or 0.89 % of reading (whichever is larger) |
| Stability | 0.1 % from -40 °C to 125 °C |
| Time constant | 16 s in air |
The sensor operates from –55 °C up to +150 °C.
The accuracy is ±0.5 °C or 0.89 % of the reading, whichever is larger.
The time constant is 16 seconds when measured in air.
