The Nuclear Power Industry trusts Tavis for some of their critical air flow controls, with very low differential pressure transducers that have been seismically qualified. So do oil companies measuring high, down-hole pressures at hot temperatures. Conventional power companies also call on Tavis for their special sensing needs. When a process requires a rugged, bulletproof, install-it-and-forget-it measurement that the cheap sensors can’t handle, a Tavis transducer or transmitter is the right sensor investment. This is especially true for applications that must monitor very low delta pressures.
Power and Industry customers have looked to Tavis for custom sensors that offer:
Power and Industry customers have looked to Tavis for custom sensors that offer:
- Integral radiation shielding

- 1 The designs above are intended to convey just a few capabilities previously used in industrial settings for discussion purposes. Tavis specializes in custom configurations and capabilities for your specific application. Our engineers will be happy to assist you with your unique measurement requirements.
- 2 Many error band definitions and limits are possible, and these actual error bands are too specific to delineate herein. A clear definition and understanding of any error band is critical, and many manufacturers’ published errors or accuracies can be very misleading. Please consult Tavis regarding your specific error band requirements.
- 3 Frequency Response given is for electronics only. Actual frequency response will depend on pressure range and media.
