Humidity Sensor Temperature/Humidity Sensor ES2-HB ES2-THB CSM ES2-HB ES2-THB DS E 3 4 Detect Humidity within an Accuracy of 3% in a Compact Body. Controller Set Provides Superior Humidity Control and Temperature/ Humidity Control. Employs high-polymer-resistive Sensor with superior durability. Compact and lightweight. Measurement ranges of 20% to 95% for humidity and 0 to 55C for temperature. Ordering Information Dimensions Note: All units are in millimeters unless otherwise indicated. Name Model ES2-HB Humidity Sensor Humidity Sensor ES2-HB ES2-THB Temperature/Humidity Sensor Temperature/Humidity Sensor ES2-THB 50 22 Humidity Sensor Module (See note.) ES2-M Note: This is a replacement item. One Module is provided with the ES2-HB/-THB. Always attach the Humidity Sensor Module when using the ES2-HB/-THB. Approximately 7 VDC will be output for the humidity output if the Module is not attached or is 50 incompletely attached. Specifications Humidity Sensor section High-polymer resistive 5.1 dia.
