AST3100-A-00200-P-3-C-0000 - American Sensor Technologies

The AST3100 is a low cost, high quality all stainless steel media isolated

Pressure Transmitter intended for use in the measurement of gases and

liquids compatible with stainless steel. The AST3100 is suitable for

automotive, industrial, refrigeration, hydraulics, offroad, construction and

agriculture applications. The AST3100 has been designed specifically for

the applications with demanding price and performance requirements.

The competitively priced AST3100 offers a choice of high level outputs.

The high strength stainless steel construction contains no silicone oil and

no internal “O” rings. Measurements are available in gauge pressure

covering ranges up to 10,000 PSI.

The AST3100 is ideal for applications needing high accuracy, excellent

long-term stability, trouble free operation, long life and high performance.

The AST3100 is backed by AST ’s one-year warranty.

OPTIONS AND SPECIALS

• The AST3100 is available with an output of

0.5-4.5 VDC, 0-5 VDC, 1-5 VDC, 4-20 mA

and 0-10 VDC. For other outputs consult factory.

• The AST3100 can be purchased with a variety of

pressure ports.

• For those applications that require unique pressure

connections, calibration, temperature compensation or

electrical connections, AST, Inc. will design and build

to the customer’s specifications.

APPLICATIONS

• The AST3100 has features that make it suitable for use

in a wide variety of applications. High vibrations and

shock, electrical noise and temperature extremes all of

which the AST3100 can handle characterize many of

these applications.

• Some of AST3100 applications include Industrial OEM

Equipment, Hydraulic Systems, Refrigeration, Offroad

and Agriculture Equipment.

PACKAGING

• The AST3100 wetted parts are made from 17-4 PH

Stainless Steel which promotes long life and resistance

to media corrosion. This high strength stainless steel

construction also provides excellent overrange and

burst protection.

• The AST3100 electrical components are protected by a

rugged stainless steel housing which is small and

lightweight for optimum compatibility with system

designs.

• As a totally self contained electronic package, the

AST3100 poly silicon sensing element coupled with a

high level output ASIC circuitry assures excellent

accuracy and long term stability.

WARRANTY

• Workmanship - AST, Inc. pressure transmitters have a

limited one-year warranty to the original purchaser.

AST, Inc. will replace or repair, free of charge, any

defective transmitter. This warranty does not apply to

any units that have been modified; misused, neglected

or installed where the application exceeds published

ratings.

• Installation/Applications - The purchaser is responsi-

ble for compatibility of the media, functional adequacy

and correct installation of the transmitter.
