The sensor is a ICP resp. IEPE type. You need a constant supply current in a range of 2mA to 8(?)mA.  You DAQ doesn't directly support this type of sensor.

You need a IEPE capable DAQ or you build or buy a IEPE supply (J-FET plus resistor and a 24V supply)  with decoupling (470µF /36V Capacitor)

Devices such as NI 9234, NI 9218, NI 9250, ... support direct connectivity to IEPE sensors.
