Temperature/Humidity Meters & Sensors Temperature/Humidity HN-C Series Temperature/Humidity Meters     The HN-C series is reliable and accurate temperature/ humidity meter with the measuring humidity range of 0 to 100%RH by using a new developed humidity sensor. Models with temperature output of 3-wire type Pt100 is available. Wall-mounting type, separated type and insertion type are prepared for various applications. Heat-resistive separated type is available for using in the environment of -40 to 180°C.,   Features Improved repeatability and reliability by a new developed humidity sensor Measurement of relative humidity 0 to 100%RH by capacitance type humidity sensor Three types of wall-mounting type, separated type, heat-resistive separated type and insertion type (soft type and hard type) are prepared for various applications. Heat-resistive separated type can be used in the environment of -40 to 180°C Easy maintenance by complete interchangeable sensors DIN rail installation enabled (except insertion type) CE conformance Models Models Types Temperature output signal HN-CQA Wall-mount type 4 to 20mADC (2-wire transmission) HN-CVA Insertion type (soft type) HN-CPA Insertion type (hard type) HN-CFA Separated type HN-CGA Separated heat-resistive type HN-CQB Wall-mount type Pt100 3-wire system HN-CVB Insertion type (soft type) HN-CPB Insertion type (hard type) …Cable length 1: 1m, 2: 2m, 3: 3m (Separated type and separated heat resistive type only) Specifications Type Wall-mount type Separated type Separated heat resistive type Insertion type (soft type) Insertion type (hard type) Model HN-CQ HN-CFA HN-CGA HN-CV HN-CP Humidity Sensor High Polymer capacitance type Measuring range 0 to 100%RH (no dew condensation) Accuracy rating ±2%RH (at 0 to 90%RH and 25°C), ±3%RH (at 90 to 95%RH and 25°C) Relative humidity/temperature coefficient ±0.1%RH/°C (at the range of 5 to 80°C) Response time Within 15 seconds (at 90% response, 25°C and under 0.1m/s wind flow) Within 1 minute (at the same condition shown left) Output signal 4 to 20mADC, 2-wire transmission (against 0 to 100%RH) Load resistance 500 or lower (at 24VDC power supply) Temperature Sensor Platinum resistance thermometer Pt100 JIS class A Measuring range 0 to 50°C -40 to 80°C -40 to 180°C 0 to 50°C 0 to 80°C Accuracy rating (for 2-wire transmission) ±0.3°C ±0.5°C ±0.3°C Output signal 4 to 20mADC, 2-wire transmission (against measuring range) for HN-CA Pt100, 3-wire system for HN-CB Load resistance (2-wire transmission) 500 or lower (at 24VDC power supply) Sensor interchangeablility Plug-in interchageable Plug-in interchangeable (including cable) Plug-in interchageable Working temperature range Meter 0 to 50°C         Sensor 0 to 50°C -40 to 80°C -40 to 180°C 0 to 50°C 0 to 80°C Power Voltage 12 to 24VDC ± 1V   Connection Crump type no-screw terminal connection Terminal connection (M4 x 5) Material Meter Resin Die-cast aluminum Protective tube ---- Resin SUS Mounting Screw fixing (M4 x 2) or DIN rail mounting Screw (M4 x 2) Flange (JIS 5K 25A) Weight About 160g About 220g About 240g About 1.6kg Accessory Fixtures for wall-mounting ---- ---- Others ---- Cable length: 1m, 2m, 3m (to be specified) ---- ---- *PDF data sheet is available at "Download Center".
