Model AXD

Operating Instructions

1.0 Introduction

Every sensor in the AXD product family has been tested and calibrated before shipment. Setra Systems 

AXD product family senses gauge, compound, vacuum gauge and converts this pressure difference 

to a proportional high level analog output. Three standard excitation and output versions are offered:

2.0 Mechanical installation

2.1 Media compatibility

The transducers in the AXD product family are offered with two different types of wetted materials. 

The AXD1 is made with 17-4PH stainless steel and the AXDH is made with 316 stainless steel. Prior 

to use in your application confirm that your media is compatible with the wetted materials of the 

ordered sensor.

2.2 Environment

The operating temperature limits of the AXD are -40° to +257°F (-40 to +125°C) on most electrical 

connection options (except where noted). The compensated temperature range is -4 to +185°F 

(-20 to +85°C).

2.3 Pressure fittings

Typically, standard pipe fittings and procedures should be used. However, for pressure ranges in 

excess of 500 psig, we suggest the use of a sealant such as Locite Hydraulic Sealant. Excessive 

torquing of metal fittings may cause a slight zero shift. The use of plastic fittings typically results in 

no noticeable zero shift. Torquing does not appreciably affect linearity or sensitivity.

2.4 Venting

Because the reference pressure in a sealed gauge transducer will vary due to changes in temperature 

and will affect overall accuracy (especially in units of less than 200 psig range), all transducers in the 

AXD product family are available in both vented or sealed pressure types.
Vented units are ordered as gauge pressure type (e.g. PSIG) units. Sealed units are ordered as 

sealed gauge type (e.g. PSIS) range units. The AXD gauge transducers  are vented through electrical 

termination as shown in table below.

3.0 Electrical installation

The AXD product family is available with four electrical terminations:

•  (2ft/0.5m, 6ft./2m, 12ft/4m, 25ft/8m) cable

•  M12-4 PIN connector

•  3-pin packard connector

•  Terminal connection w/ conduit adapter, 1/2 inch
