Pressure sensor with approximately 100 psi working range, but 10,000 psi proof pressure.
Pressure sensor with approximately 100 psi working range, but 10,000 psi proof pressure.
(OP)
I am in need of a pressure sensor that can accurately (within +/- 5 psi) measure pressures within the 0-200 psi range or so, but have a proof pressure that is >10,000 psi. Does something like this exist off-the-shelf?
We tried using this, but we found it wasn't accurate enough in the range we cared about (0-200 psi). We need accuracy on the order of +/- 5 psi or so.
This is for a 10,000 psi hydraulic pump.

The Honeywell STG79L has a maximum span of 10,000 PSI but has a turn-down of up to 100:1. Its Maximum Allowable Working Pressure (MAWP) is 10,000 PSI
For 50:1 turndown with a range of 0-200 PSI over the 4-20mA output, the calculated accuracy at reference conditions is ±0.45% of span for turndown and potential 0.17% of span for 50°F temperature effect above/below reference. Figure about ±1 PSI.z The gauge pressure spec sheet has a document #34-ST-03-102.
These kinds of transmitters are not fixed range, they need to be configured for a specific output range, The task of configuring an output range requires either
- an optional keypad and display (availability is vendor dependent) so that you can range it
- the wherewithal to configure it with HART (handheld communicator or software and modem)
- have the vendor range it for you
Other brands are likely similar in their offerings.
