HN-EK

Product catalog summary

Overview: The HN-EK series is a wall-mounting temperature and humidity meter designed for high accuracy measurements, ideal for environments like pharmaceutical storage and incubation rooms. Its thin design minimizes external disturbances, and it features easy maintenance through sensor unit exchange.

Features:

High accuracy measurement by reducing heat conduction effects from the installation surface.
Easy maintenance with exchangeable sensor units.
Thin design suitable for various installation locations.

Configuration and Models:

Output signals available in two configurations: 4 to 20mADC (2-wire transmission) for both temperature and humidity, or Pt100 (3-wire) for temperature and 4 to 20mADC for humidity.
Models include HN-EKA1N and HN-EKB1N, each with specific output and sensor configurations.

Specifications:

Humidity Sensor: High-polymer capacitance type, measuring range 0 to 95%RH, accuracy ±2%RH.
Temperature Sensor: Platinum resistance thermometer, measuring range -10 to 55ºC, accuracy ±0.3ºC.
Response time: Humidity within 15 seconds, temperature within 10 minutes.
Power Supply: 12 to 24VDC, with specific resistance load requirements.
Installation: Compatible with general-purpose embedded boxes, with a standard thermoplate to reduce heat conduction from large surfaces.

Compliance and Standards:

CE Marking: EMC Directive 2014/30/EU, EN61326-1:2013 Class A.
RoHS Compliance: 2011/65/EC, EN50581:2012.

Additional Information:

Humidity converter HN-GV available for HN-EKA1N, converting outputs to various humidity-related metrics.
Annual sensor unit exchange is recommended for maintaining accuracy.
