The EE33 sensor from E+E measures humidity and temperature from -40 °C to 180 °C with high accuracy and robust IP65 protection.
The EE33 humidity/temperature sensor is designed for stable, accurate measurements in harsh environments, offering a wide temperature range (-40 °C to 180 °C) and pressure tolerance up to 100 bar. It features a monolithic sensing element with proprietary E+E coating and multiple heating modes to prevent condensation and chemical contamination.
The device provides two scalable analog outputs, RS232/RS485 digital interfaces, and optional alarm relays. Various remote probe types and enclosure options (polycarbonate or metal, IP65/NEMA 4) allow customization for specific applications.
| Relative Humidity Measuring Range | 0‑100 %RH |
|---|---|
| Pressure Rating (pressure‑tight probes) | up to 100 bar (1450 psi) |
| RH Accuracy | ±(1.3 + 0.003 × mv) %RH |
| Temperature Accuracy | ±0.005 °C/°C |
| Analog Output Range | 0‑10 V or 4‑20 mA |
| Enclosure Protection | IP65 / NEMA 4 |
The sensor uses a Condensation Prevention heating mode that heats the sensing element when a configurable RH setpoint is reached.
The EE33 is offered in a polycarbonate housing (IP65/NEMA 4) or a metal (AlSi9Cu3) housing with the same protection rating.
