Yokogawa has released a range of wireless instruments including pressure, differential pressure and temperature sensors. They are designed to provide accurate transmission of data with virtual zero bit rate error up to 600 m, without the need for special antennas.
Emerson Process Management has expanded its Profibus offering to include the Rosemount 2051 pressure transmitter. The current portfolio of the Rosemount 3051 and 2051 pressure transmitters and the Rosemount 644 temperature transmitter are now available with Profibus PA profile V3.02.
The Keller 23 SY/25 Y pressure transmitters feature extremely small temperature error, which is achieved using an additional circuit containing a temperature sensor that subdivides the temperature range into fields that are 1.5 K wide.
The Series 629 differential pressure transmitter monitors differential pressure of air and compatible gases and liquids with 0.5% accuracy.
Noshok electronic indicating pressure and temperature transmitter/switches provide local monitoring, 4-20 mA current output and switching control.
Noshok offers a variety of cost-effective orifices and snubbers to protect valuable instrumentation from pulsation and pressure spikes by restricting the flow of rapidly increasing and decreasing pressures.
WIKA has developed the MG-1 pressure transmitter for the pressure measurement of medical gases and, in particular, of oxygen. The MG-1 uses materials that are specifically suited to medical oxygen applications and are approved by the German Federal Institute for Materials Research (BAM).
The Series MS Magnesense differential pressure transmitter is designed for monitoring pressure and air velocity. It features field-selectable English or metric ranges, a field-upgradeable LCD, adjustable damping of the output signal (with optional display) and the ability to select a square root output for use with pitot tubes and flow sensors.
The Keller Series 33 X and 35 X pressure transmitters are mathematically compensated to achieve up to 0.01% FS precision. The highly precise pressure transmitters are available in pressure ranges from 1 to 1000 bar. Both analog and digital outputs are simultaneously available, and the Series 33 X and 35 X are fully programmable.
The Series 628CR ceramic sensor pressure transmitter is claimed to be accurate to ±1% of full scale and contains a low-cost ceramic sensor housed in a compact, rugged, NEMA 4X stainless steel body.
The PSD-30 pressure switch is available with an optional fieldbus-independent communications interface, IO-Link.
The Noshok 640 series heavy-duty pressure transducers feature diffused semiconductor and sputtered thin-film technology to provide maximum stability. They are designed for industrial and laboratory applications requiring high accuracy and repeatability, such as research and testing, aeronautical, precision controls, marine, power generation and medical applications.
The series DX differential pressure switch makes a contact output based on the differential between two pressure sources and its wetted materials of brass and fluoroelastomer are suitable for use with most gases and water-based solutions.
The Jumo Midas S05 pressure transmitter is a completely welded measuring system made of high-quality stainless steel and can be used in almost all substances, even under rough conditions.
The FiberSensing extended temperature BraggMeter is a low power measurement unit for operation over an extended temperature range, specifically designed to interrogate fibre Bragg grating (FBG) sensors in severe environmental conditions.
