Overview
The Omega 402B-T-F temperature indicator is a digital panel meter designed for direct thermocouple input in industrial monitoring and control systems. This multi-input model features five separate thermocouple channels with easy front-panel selection, eliminating the need for manual recalibration between sensors. The unit delivers reliable temperature readings across multiple process points, supporting both Fahrenheit and Celsius scales via accessible DIP switch configuration.
Key Features
- 5-Channel Thermocouple Switching: Front-panel pushbuttons allow rapid switching between up to five thermocouple inputs without interrupting operation.
- 1° Standard Resolution: Provides accurate temperature display with 1-degree resolution across the operating range.
- °F/°C Selectable: Miniature DIP switch behind the front panel enables quick conversion between temperature scales.
- Isolated Electronics: Superior low-noise analog-to-digital conversion with multi-segment linearization for laboratory-grade accuracy.
- Screw Terminal Connections: Rear-mounted terminals accept up to five thermocouple sensor inputs for secure, industrial-grade wiring.
