Dpstar is a leader in environmental and industrial measurements. Curiosity and innovation are core values in our company. Our extensive knowledge and expertise are materialized in our selection of innovative products. Accurate measurements are essential for healthy indoor air and improving the energy efficiency of buildings. The unique, cutting-edge Dpstar sensor technologies are manifested throughout our versatile range of products. The transmitters have an exceptionally long lifetime and excellent measurement stability, thus being practically maintenance-free. These are among the many reasons why Dpstar’s products are a sustainable choice.

HMS80 Series INTERCAP Humidity and Temperature Transmitters are designed for outdoor measurements in various building automation applications. These ±3 % transmitters include an integrated radiation shield to reduce the influence of solar radiation on temperature and humidity measurements.

Dimensions

Easy Installation

HMS80 transmitters are easy to install. They can be mounted directly onto a wall or pole without any extra accessories. There are no loose parts, screws are retained in the enclosure, all connectors are clearly labeled, and the connectors are within easy reach. For fast and convenient configuration, the most popular control parameters in free cooling control – dew point temperature, wet bulb temperature, and enthalpy – are selectable using DIP switches.

Low Maintenance

HMS80 series transmitters require minimal maintenance thanks to their excellent sensor stability and high-quality materials. If necessary, the INTERCAP sensor can easily be replaced in the field with minimum downtime.

Applications

A reliable basic outdoor humidity sensor for a pole or wall installation. Dew point, wet bulb, and enthalpy outputs can be selected by dip switch instead of the default RH output. 5-year warranty is valid for instruments purchased in 2021 and beyond. The Humidity and Temperature Sensor Transmitter Series HMS80 are optimized for outdoor measurements HVAC. They feature an integrated solar radiation shield, which is a must for accurate humidity and temperature measurements in outdoor conditions. Both 2-wire HMS82 and 3-wire HMS83 versions are available.
