Relative humidity and temperature sensor HTS401

wall-mountPCBdigital

The HTS401 delivers modern humidity and temperature measurement that is fail-safe, precise and ready for the most demanding environments. With measurement accuracy up to ±0.95 % RH and ±0.1 C (0.18 F) and an operating range from −40 C to 80 C (−40 to 176 F), the HTS401 integrates flexibly into diverse applications, from outdoor installations to cleanroom environments.The rapidX measuring module can be replaced in 10 minutes without toolsPrecise process control and tangible energy savings in operationCalibration is straightforward and automatically provides a digital 3.1 inspection certificate, making the HTS401 ideal for validated or documentation-critical processes.Industrial processes place stringent demands on instrumentation. Extreme ambient conditions, aggressive media, chemically intensive cleaning and the need for accurate, fail-safe data are common. Conventional sensors soon reach their limits because of condensation, corrosion, temperature extremes or labour-intensive maintenance. This is where the HTS401 excels.With a robust and intelligent protection concept that combines the EE sensor coating with connection encapsulation, the HTS401 remains ready for service even under severe stress. The Automatic Recovery function (ARC) protects the sensing elements against adverse chemical influences. In the event of condensation risk, the Condensation Guard (CG) intervenes before measurement performance is affected.Typical Applications:High-end HVAC: data centers, swimming halls, outdoor applicationsAgriculture: greenhouses, stables, storage and ripeningPharmaceutical Industry: cleanroom monitoringFood and beverage: meat & cheese maturationKey Features:Protective Sensor CoatingrapidX TechnologyAutomatic ReCovery (ARC)Condensation Guard (CG)IP65 / NEMA 4X protection ratingAll RH related physical quantitiesModbus RTUTechnical Data:Measuring range Humidity: 0...100% RHAccuracy Humidity: -15...40 C Measuring range Temperature (wall mount): -40...60 C (-40...140F)Measuring range Temperature (duct mount): -40...80 C (-40...176F)Accuracy Temperature: ±0.1 C (0.18F)Accuracy Humidity: ±0.95 % RHAnalogue outputs: 0-5V, 0-10V, 4-20mA, 0-20mA (3-wire)Advantages of HTS401 with EE Sensors:Reliable operation under condensation and chemical load: ARC, heated sensing unit (Condensation Guard), and protective coating shield the sensor from high humidity, aggressive media, and cleaning residues. Fully potted electronics and sealed module connection reduce corrosion-related failures, measurement drift, and maintenance.Maintenance without process interruption: rapidX technology allows sensor module replacement in the field without tools in just 10 minutes. Each rapidX sensor is factory pre-calibrated and delivered with a digital inspection certificate according to DIN EN 10204-3.1.Reduced failure risk through active condensation protection: Integrated Condensation Guard actively heats the sensing element to prevent dew formation, ensuring stable output even in high-moisture applications.High accuracy for stable control: Delivers ±0.95 % RH and ±0.1 C accuracy, with internal calculation of derived humidity parameters such as dew point, mixing ratio, and enthalpy. Wide operating range (-40 C to 80 C).Easy system integration: Supports RS-485/Modbus RTU, analogue outputs, and PCS10 configuration. Wall-mount, duct, and remote-probe variants available.
