Description

GOVERNMENT RIGHTS

[0001] This invention was made with government support under contract number DE-AC0676RL01830 awarded by the U.S. Department of Energy. The Government has certain rights in the invention.TECHNICAL FIELD

[0002] The invention relates to sensors. The invention also relates to valves and process control. BACKGROUND OF THE INVENTION

[0003] Industrial process control environments typically require physical sensing of parameters such as temperature, pressure, flow rate, strain, displacement, humidity, vibration, etc. Adapting a sensor network and its cabling infrastructure to existing plant environments is usually cost prohibitive.

[0004] Various sensors that incorporate transmitters are known in the art. For example, U.S. Pat. No. 5,774,048 (incorporated herein by reference) relates to a valve that generates a wireless transmittable signal if pressure drops within vehicle tires. U.S. Pat. No. 6,005,480 to Banzhof et al. relates to similar subject matter.
