High Measurement Accuracy, Easy Data Integration 
The HTP501 measures the relative humidity and temperature in an operating range of -40 to 120 °C (-40 to 248 °F). The high-quality E+E humidity sensing element, temperature compensation and configurable pressure compensation ensure excellent measurement accuracy. In addition to the measured humidity and temperature values, the sensing probe calculates further humidity-related physical quantities such as the dew point temperature, absolute humidity or mixing ratio. The measured data are available on the RS485 interface and can be easily integrated into process control using the Modbus RTU protocol.

Optimised for Harsh Environmental Conditions
The probe features a rugged IP66 stainless steel enclosure, a high-temperature cable with moulded M12 connector, and a choice of different filter caps. The electronics are well protected inside the probe and therefore safe from condensation and corrosion. The E+E proprietary coating protects the humidity sensing element and its leads against dust and corrosive deposits, ensuring excellent measuring performance and long-term stability in harsh conditions. An optional sensor leads protection helps to significantly extend the service life of the sensing element in particularly aggressive environments.

Flexible and Extensible
Two probe lengths (200 mm and 400 mm) and three different cable lengths offer the user a huge degree of flexibility when installing the HTP501. The free PCS10 configuration software facilitates the setup and supports individual configuration of the probe. The HTP501 is compatible with the Sigma 05 sensor hub by E+E Elektronik. The digital sensing probe can be plugged into the host device based on the plug-and-play principle and thus extended to a sensor unit with display and analogue outputs.
