DSI-CHG
Charge Sensor Adapters

DSI-CHG adapter is intended for charge accelerometer or microphone sensors with BNC connector. The range is up to 50000 pC. AC coupled with 0.07 Hz. Max. 100 kHz bandwidth.

DSI-CHG-DC is an adapter used for the measurements with charge sensors. It has four input ranges from 1 kpC up to 500 kpC. In addition to the DC measurement, users can choose four different hardware high-pass filters in the channel setup of Dewesoft X3 software. 

The main advantage of the DSI-CHG-DC adapter is a large time constant, practically DC charge measurement with DC drift lower than 0.1 pC/s for the 500 kpC input range. The bandwidth of DSI-CHG-DC is 20 kHz for the 500 kpC range and 200 kHz for the 50 kpC range. DSI-CHG-DC is currently supported by all SIRIUS DAQ amplifiers with DSUB9 input connectors and KRYPTON STG amplifiers. Host amplifier configuration and calibration coefficients can be read via TEDS.

Charge sensors can be connected to the DSI-CHG-DC BNC input connector and to the host amplifier using DSUB9 male-female extender cable. The housing includes four holes and two belt clips for easy mounting of the DSI-CHG-DC adapter.

DSI-LVDT
Adapters For Linear Variable Differential Transformer (LVDT) Sensors

DSI-LVDT is an adapter for connecting LVDT sensors. It generates 4 to 10 kHz excitation for LVDT sensors and includes phase adjustment with a potentiometer. Output 1 V = 1000 mV / V.

See article Measuring Position and Displacement With LVDT Sensors.

DS-16xLVDTr
Adapter Box for LVDT Sensors

DS-16xLVDTr uses a unique ratiometric architecture to eliminate several of the disadvantages associated with traditional approaches to LVDT interfacing. DS-16xLVDTr combines 16 channels of DSI-LVDT adapters in a 19”-rack compatible housing with 1U height.

The main advantage of the new design is the asynchronous excitation signal provided from an external function generator to a BNC front connector (IN connector). When using multiple DS-LVDTr devices the EXC signal can be daisy-chained from the BNC OUT connector to the BNC IN connector on the other device.

There are 16 DSUB-9M male connectors on the front panel for the connection to the Dewesoft data acquisition system. Each connector includes a trimmer for phase adjustment.

On the back panel are 16 DSUB-9F (female) connectors for the LVDT sensor connection. DS-16xLVDTr supports measurements with full-bridge and half-bridge LVDT sensor types.

More details about DS-16xLVDTr can be found in the user manual.

See article Measuring Position and Displacement With LVDT Sensors.
