New DSI Adapters: Universal Thermocouple, Waterproof Current Shunt, and IEPE Adapters
February 27, 2023
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.

DSI-ACC-0.16Hz-20mA: IEPE/ICP® adapter
DSI-ACC-0.16Hz-20mA is the new DSI adapter for IEPE/ICP® signal inputs.
The adapter combines features of existing DSI-ACC adapters with an increased time constant (𝜏 = 1 s, high-pass filter 0.16 Hz) and sensor excitation (20 mA).
DSI-ACC-0.16Hz-20mA is supported only with the following host amplifiers: SIRIUS LV/LV+, STG/STG+, HS-LV/HS-LV+, HS-STG/HS-STG+.

| 1000 mV | up to 110 dB (limited by the SNR of the host amplifier) |
DSIw-20mA: waterproof IP67 current shunt adapter
DSIw-20mA is a waterproof DSI adapter for current measurement with up to 20mA.
It uses a 50 Ω shunt resistor with 0.01 % accuracy and 0.2 ppm/K temperature drift (0.05 ppm/K in the temperature range 0 °C to 60 °C).
This is a product made for sensing current from industrial sensors with 4-20 mA output in harsh environments. It is designed with a double DSUB9 adapter hood (IP67 rating).
DSIw-20mA is suited for mounting on a SIRIUSwe or KRYPTON STG.
