The HTP501 humidity and temperature sensor from E+E Elektronik is intended for use in drying chambers and other demanding industrial applications. The stainless steel probe offers high measurement accuracy and a temperature range of -40 to 120 °C. The measured values are available on the RS485 interface with Modbus RTU protocol.

Optimized for harsh environmental conditions

The HTP501 is characterized by a robust IP66 stainless steel housing, a high-temperature cable with molded M12 connector and a selection of different filter caps. The electronics are well protected inside the probe and are therefore safe from condensation and corrosion. The E+E sensor coating protects the humidity sensor element and its solder joints from dust and corrosive deposits, thus ensuring excellent measurement performance and long-term stability under harsh conditions. An optional encapsulation of the sensor connections (sensor connection encapsulation) can significantly extend the service life of the sensor element in particularly aggressive environments.

High measurement accuracy, easy data integration

The HTP501 measures relative humidity and temperature in a working range of -40 to 120 °C. The high-quality E+E humidity sensor element, temperature compensation and configurable pressure compensation ensure high measurement accuracy.

In addition to the measured humidity and temperature values, the probe calculates other humidity-related variables such as dew point temperature, absolute humidity or mixing ratio.

The measurement data is available via the RS485 interface and can be easily integrated into the process control via Modbus RTU protocol.

Flexible and expandable

Two probe lengths (200 mm and 400 mm) as well as three different cable lengths offer the user a high degree of flexibility when installing the HTP501. The free PCS10 configuration software facilitates the setup and allows an individual configuration of the probe.The HTP501 is compatible with the Sigma 05 sensor hub from E+E Elektronik. As a result, the digital sensor can be expanded in a plug-and-play principle into an independent sensor unit with display and analog outputs.
