Pressure Sensor with Built-in Amplifier VMSI/VMSV series

A New Standard for Pressure Sensor with Built-in Amplifier

Pressure Sensor with Built-in Amplifier
VMSI/VMSV series

Compact, High-accuracy and Capable of Measuring Pressures
in Various Industries and Applications under any Conditions

The VMSI/VMSV series pressure sensors with built-in amplifier are specialized for medium and high pressure ranges of 1 to100 MPa. Though compact and lightweight in design, these models offer a high accuracy of ±0.5%F.S. (at 25°C) and can be used in the temperature range of −40 to 120°C. Moreover, they are IP67-rated, have superior vibration and shock resistance, and are suitable for many different applications.

[For mass production only] Custom-made pressure transmitter VMS series is also available.
