Installation Guide

“Multi-Sense” Model 260 Series

Multi-Range Differential Pressure Transducer

MECHANICAL INSTALLATION

Mounting Position

Mount and calibrate in vertical position for quick and easy installation
on ducts, w alls or c eilings and in c ontrol r ooms .

GENERAL INFORMATION

Every Model 260 has been calibrated and tested before shipment to guarantee
performance for all pressure ranges.

The Model 260 is available in four versions, which have field selectable range
capability via a slide switch. See four versions below:

MULTI-SENSE RANGE SPECIFICATIONS

Model MS2 1.0”, 2.5”, 5.0” and 10” W.C. FS +/- 1.0”, 2.5”, 5.0” and 10” W.C. FS
Model MS3 25, 50, 100 and 250 Pa FS +/- 25, 50, 100 and 250 Pa FS
Model MS4 .25, .50, 1.00 and 2.5 kPa +/- .25, .50, 1.00 and 2.5 kPa

Media Compatibility

Model 260 transducers are designed to be used with air or
nonconducting gases.

Use with liquids or corrosive gases will damage the unit.

Environment

The operating temperature limits of the 260 are as follows:
Operating Temperature 32°F to 122°F (0°C to 50°C)

Compensated Temperature Range 32°F to 122°F (0°C to 50°C)

SIMPLE 5-STEP SETUP INSTRUCTIONS - STEPS 2 - 5

Power On - LCD Display

Display momentarily toggles thru all existing setup parameters on initial power
up. Pressure is normally indicated on display. Units are either in inches of water
column (WC) MS1 & MS2, or Pascal (Pa) MS3 & MS4.

*STEP 2: Select Pressure Range: Set

appropriate full scale range using
the Slide Switch Multiplier.
LCD will momentarily indicate
selected range.

STEP 3: Select Unidirectional

or Bi-directional mode.

STEP 4: Select Current (mA)

or Voltage 1-5, 0-5, or
0-10 VDC output range.

*Step 2 will follow same
instructions for other inches of
water column and pascal
ranges.
