Dewesoft is introducing 3 new DSI adapters compatible with Dewesoft data acquisition systems:
- DSI-TH-UNI: Universal thermocouple adapter
- DSI-ACC-0.16Hz-20mA: IEPE/ICP adapter
- DSIw-20mA: Waterproof IP67 current shunt adapter
DSI-TH-UNI: Universal Thermocouple Adapter
This new DSI adapter for thermocouple sensors features a universal thermocouple input. It allows it to connect practically any type of thermocouple sensors - K, J, T, R, S, N, E, B, C.
DSI-TH-UNI has integrated cold junction compensation with CJC accuracy of 0.5 °C.
Universal thermocouple DSI adapter comes in an attractive compact chassis-mounted directly on the host amplifier without any additional cable.
Host amplifier configuration and calibration coefficients can be read via the TEDS sensor interface.
