ES1B

Overview of Omron ES1B Infrared Thermosensor

The Omron ES1B is an infrared thermosensor designed to provide accurate, stable, and contactless temperature measurement in industrial applications. It outputs a signal equivalent to a K-type thermocouple, allowing easy integration with standard temperature controllers and alarm units. The sensor comes in four temperature range models covering 10 to 260°C and features a quick 300 ms response time with high reproducibility within ±1% of its range.

Key Features of Omron ES1B

• Non-contact Temperature Measurement: Provides reliable temperature sensing without physical contact with the target object, minimizing wear and maintenance.[web:327]
• Thermocouple Equivalent Output: Outputs a millivolt signal similar to a K-type thermocouple for direct connection to temperature controllers.[web:327][web:329]
• Multiple Temperature Ranges: Available in 10-70°C, 60-120°C, 115-165°C, and 140-260°C variants to suit diverse industrial needs.[web:327]
• High Accuracy and Reproducibility: ±1% PV or ±1°C reproducibility and accurate range-dependent measurements with minimal temperature drift.[web:328][web:329]
• Fast Response: Approximately 300 ms for a 63% response rate, suitable for real-time temperature control.[web:329]
• Durability: Silicon-based cable with PVC covering offers resistance to dust, water, and temperatures up to 70°C; IP65 rated for protection.[web:327][web:329]
