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:
  • Integral radiation shielding
  • Internal heater-controlled for added accuracy
  • Either 2- and 3-wire current loop (4-20 mA) outputs or 4-wire voltage outputs
  • 110 VAC operation
  • Very Low Delta Pressure, some with high line and overpressure capability
  • Fully sealed environmental enclosures or all-welded designs
  • Seismic Qualification
  • Acoustic tolerance
