Sensor solution A high temperature charge-mode accelerometer KS56 (up to 250°C) can be connected to the input of the hand-held vibration meters VM22/23/24/25 via the Pre-Amplifier Model VM2x-A. We recommend the 1.5 m sensor cable 009/T-UNF-UNF-1.5. VMID is not supported with this solution. for high temperatures up to 250°C
