MultiCal

bar/PSI Pressure Module

PN: 1527, 206 bar/ 3000 PSI

INSTRUCTION SHEET

Introduction

The MulitCal™pressure modules can be used to measure almost any type of pneumatic

or hydraulic pressures, up to

3000 PSIG. It can also be used to

measure vacuum..

The module does not have a display.

Instead, the MultiCal converts

pressure (or vacuum) to milliVots.

The module must be used with

a device capable of measuring

milliVolts DC, such as a digital

multimeter (DMM).

The MultiCal is calibrated to convert

pressure units (bar or PSI) to 1 mV per pressure

unit. Vacuum readings will of course be negative.

Pressure is measured by connecting your pressure source to the

” female NPT ﬁtting

of the pressure transducer. Any gas or liquid compatible with 316 stainless steel may be

applied to the module as the pressure source.

The three-position switch acts as a power switch as well as selecting inches PSI or bar

scaling for the output. Also, the OFF position allows you to read the battery condition via the

external multimeter.

The module performs best when used with high accuracy multimeters. We recommend any

of the following meter:

Fluke 70 series, 80 series, Model 45

Any meter with 10MΩ or greater input impedance and 4mm banana jacks on 3/4” centers.

Typical uses. for the module are to calibrate pressure gauges and pressure transmitters.

When used with a high performance multimeter, the pressure adapter becomes more

than just a “digital pressure gauge.” For example, use the datalogging features built-in to

the Fluke 87 and you’ll have a system that can measure and record peak (high) pressures,

peak low and average pressures of varying or unstable pressure source.
