Here's how some of our customers use this product...

Rugged and Reliable with a Short Lead Time

The Background: Our customer is an industrial systems integrator currently working on a project which requires a n umber of submersible level sensors which will be installed in outdoor storage tanks.

The Problem: The customer wants a rugged, reliable, and accurate option that can be delivered quickly.

The Solution: We suggested the KPSI 700 series level transducers. Available with lightning protection, hazardous area approvals and a quick delivery, the 700 series fits the requirements of most submersible level applications. The aneroid bellows provides customers with zero maintenance moisture protection while the vent filter option ensures that customers don't sacrifice any accuracy.
