Model Selection

Example

Selection of Pressure sensor

Refer to Selection Table for Pressure Sensors for specification and model numbers and specify the desired model.
[e.g.] VPC - A3B1 - S - A - 1.000MPa - 1 / VPRQ - 1MP

Selection of Power converter

Only when AC power is used, refer to the Power Converters page, and specify the model.
[e.g.] TUC - AC100V - 3 - 1N

  A1 1mV/digit (±1999mV max.) 1.2kHz This value has been calculated as response frequency (= 1/2T (Hz)) based on the measured step response (0–100%) and rise time (T) with the sensor bridge resistance of 350Ω.
Response frequency is determined by the sensor to be used. Consult with us when focusing on response.
