Ashcroft offers the assembly of SMART transmitters to

our diaphragm seals and isolation rings, ensuring that

your pressure assemblies are tested for accuracy and

leak integrity prior to shipment. Our transmitter assembly

service helps to take the guesswork out of specifying

the correct pressure instrumentation and assembly

orientation, while our Ashcroft instrumentation experts

ensure that the instruments are compatible and properly

calibrated to suit your application.

Selection is easy: choose the transmitter you want us

to attach and configure the appropriate assembly code

according to the instructions in this document. We’ll build

the assembly with our custom-made low volume fittings

for minimal temperature error, fill the assembly with our

state-of-the-art vacuum filling system, and ensure that

every instrument in the assembly is checked for calibration

prior to shipment.

To ensure compatibility with the seal or isolation ring being

attached, we recommend the following:

■

Note the instrument connection: make sure all

instruments being attached are the same size NPT

■

Note the required output span – make sure it does not

exceed the pressure rating of the isolator or the ranges

of any attached instrument.

■

Remove any option codes for block and bleed valves

from the transmitter manufacturer part number– these

cannot be installed above a diaphragm seal.

If in doubt, submit the form found at

https://bit.ly/transmitterform and we’ll respond within 24

hours with our recommendations.

Refer to the coding table on pages 2 thru 3 to select the

appropriate coding for the assembly orientation you need.

When ordering, be sure to include the full transmitter part

number somewhere on the purchase order. Refer to the

respective data sheets to configure part numbers for

isolation rings, seals, and any other instrument included

on the assembly. (see coding example on page 4)

Working through your Ashcroft sales representative or

authorized distributor, submit your order. Once it has

been entered into our system, we will issue a return

authorization number for your transmitters.
