Rugged instrumentation, shock resistant

[PSMChE]

We have a portable wastewater treatment process that is going to be skid mounted for a client to treat water used in oil well drilling in remote areas. In the past they have had instrumentation and electronics used on other skids fail due to the harsh treatment they receive during transportation and use (these skids get bounced around quite a bit going up mountains on logging roads and just from general abuse that roughnecks tend to put on their equipment).

I am looking to specify instrumentation for our process (flow, pressure, pH, level switches, level indicators and the like) to be as rugged and shock resistant as possible as well as weather proof. Our normal instrument supplier doesn't seem to have the grade of instrument that I need.

Can anyone recommend a supplier or manufacturers that would be able to supply the type of rugged instruments I need? I was thinking military grade type equipment but I haven't had any luck finding anything.

Any help is appreciated.

Rosemount should handle the pressure, some flow and even some level technologies. However, I think that spare parts will be the trick for pH.

While most field instrumentation can handle some amount of dropping, etc., they probably are not sufficiently rugged to deal with the environment described.

This is where you'd hire somebody to design a ruggedization package, consisting of shock isolators, etc., or do that yourself.

And hire a field technician. We have that exact same scenario and our electrician goes all over the countryside.
Rosemount is good
