The MKS Type 270D High Accuracy Signal Conditioner is designed for the MKS 300 and 600 Series Baratron high accuracy pressure sensors. Three versions are available with different display capabilities: a 4½ digit, 5½ digit, and a displayless unit. All versions are designed to fit in a standard ½ rack mount.

The 270 instrument consists of power supplies, an oscillator, and the heater supply necessary to interface with the compatible MKS 300 Series or 600 Series pressure sensors. The pressure can be read in mmHg, mbar, kPa, inHg, inH2O, cmH2O, and psi. The 270 instrument can be combined with the Type 274 multiplexer unit to provide signal conditioning for up to three pressure sensors (from either the 300 or 600 Series, or a combination of both). The 270 controller interfaces with a pressure sensor through its HEAD and MULTIPLEX connectors.
