摘要： A process device wireless adapter (300, 600, 700, 800) includes a wireless communications module (310, 602, 702), a metallic housing (302, 606), and an antenna (320, 604, 826). The wireless communications module (310, 602, 702) is configured to communicatively couple to a process device (350) and to a wireless receiver (502). The metallic housing (302, 606) surrounds the wireless communication module (310, 602, 702) and has a first end and a second end. The first end is configured to attach to the process device (350). In one embodiment, a metallic shield (608, 708) contacts the housing (302, 606) second end such that the metallic shield (608, 708) and the housing (302, 606) form a substantially continuous conductive surface. The antenna (320, 604, 826) is communicatively coupled to the wireless communication module (310, 602, 702) and separated from the wireless communication module (310, 602, 702) by the metallic shield (608, 708). Preferably, the wireless communications module (310, 602, 702) illustratively includes a printed circuit board that has a length that is greater than its width.

摘要： A multivariable process fluid pressure transmitter (10) includes an electronics module (18) and a sensor module (222). The sensor module (222) is coupled to the electronics module (18). A process fluid temperature sensor is coupled to the process fluid pressure transmitter. A differential pressure sensor (228) is disposed within the sensor module (22) and is operably coupled to a plurality of process fluid pressure inlets. A static pressure sensor (230) is also disposed within the sensor module (222) and is operably coupled to at least one of the process fluid pressure inlets. A first temperature sensor (232) is disposed within the sensor module (222) and is configured to provide an indication of a temperature of the differential pressure sensor (228). A second temperature sensor (234) is disposed within the sensor module (222) and is configured to provide an indication of a temperature of the static pressure sensor (230). Measurement circuitry (328) is operably coupled to the differential pressure sensor (228), the static pressure sensor (230), and the first (232) and second (234) temperature sensors. A processor (326) is coupled to the measurement circuitry (328) and is configured to provide a compensated differential pressure output based on a measurement of the differential pressure sensor (238) and the first temperature sensor (232), and to provide a compensated static pressure output based on a measurement of the static pressure sensor (230) and the second temperature sensor (234).

摘要： A field device detects the presence of fluid in the terminal block area of the field device by generating an alternating current (AC) test current signal and measuring the amplitude of the resulting AC voltage signal. The field device includes a first terminal and a second terminal adapted for connection to a control room through a twisted-wire pair current loop. Impedance of the current loop is increased by the presence of fluid between the first terminal and the second terminal. By providing an AC test current signal to the control loop and measuring a resulting AC voltage magnitude, the impedance of the control loop can be determined. Increased impedance in the control loop indicates the presence of water in the terminal block.

摘要： A process fluid sensor 104 for sensing a characteristic of a process fluid is provided. The process fluid sensor 104 includes a metallic sensor body 150 that defines a chamber therein. A piezoelectric crystal element 160 is disposed proximate the chamber and is configured to generate an electrical signal in response to a mechanical input. The piezoelectric crystal element 160 is mechanically coupleable to the process fluid, but is sealed within the sensor body 150 with the exception of a gaseous pathway (164). A vortex flowmeter (100) utilizing the process fluid sensor (104) is also provided.
