Ordering Information Name Model Humidity Sensor ES2-HB Temperature/Humidity Sensor ES2-THB 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 incompletely attached. Specifications Humidity Sensor section Note: 1. The maximum ripple voltage of 2% p-p max. The recommended power supply is the OMRON S82K. 2. ES2-THB only. 3. Do not use or store the Sensor for an extended period at a humidity of 90% or more. 4. Pt100 (JIS C 1604-1989) is used for the measuring elements. Set Pt100 for input sensor type of the Temperature Controller. Dimensions Note: All units are in millimeters unless otherwise indicated.
