The United Electric Controls One Series electronic pressure switches and electronic temperature switch have a fully adjustable set point and deadband and 0.1% repeatability, and area available in Type 4X enclosures for explosion-proof and non-incendive area classifications.
The UNIK 5000 pressure-sensing platform from the Sensing business of GE Measurement & Control Solutions now carries FM and FMc approvals in addition to its existing IECEx/ATEX intrinsically safe certifications. As a result, UNIK 5000 pressure sensors can now be used worldwide in hazardous zone applications in the oil and gas and process industries, as well as in mining.
Advanced diagnostics embedded in a pressure transmitter can proactively detect abnormal process conditions.
The BPS series of pressure sensors from Balluff have IP 67 protection for use in gaseous and liquid media. The rugged devices feature a high-quality, long-term stable ceramic load cell, simple installation and high precision. A large, bright and easily visible display shows status - the current system pressure in bar, mbar, psi and MPa - and also features fast and simple configuration of the sensors according to the VDMA standard, using two keys and intuitive menu guidance.
The Yamatake AT9000 Advanced Transmitter is a microprocessor-based smart transmitter that features high performance and stability. Capable of measuring gas, liquid, vapour and liquid levels, it transmits 4-20 mA analog and digital signals according to the measured differential pressure.
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.
