Differential pressure transmitters

230 Setra wet/wet differential pressure transducer

The 230 Series is designed for wet-to-wet differential pressure measurements of liquids or gases. They feature fast-response capacitance sensors that respond approximately 20x faster than conventional fluid-filled transducers! Sensors are coupled to signal conditioned electronic circuitry for highly accurate, linear analogue output proportional to pressure. Both unidirectional and bidirectional models are available for line pressures up to 250 psi. These units feature bleed ports that allow for total elimination of air in the line and pressure cavities

265 Setra Low range differential pressure transducer

The 265 Series are low-pressure transducers for ranges as low 0.25˝ W.C. and feature ±1% full scale static accuracy. Primarily used in Building Energy Management, these transducers are capable of measuring pressures and flows with the accuracy necessary for proper building pressurisation and air flow control. 265 Series transducers utilise an all-stainless steel micro-tig welded sensor that allows up to 10 psi overpressure (in either direction) with no damage to the unit. All sensor components have thermally matched coefficients, which promote improved temperature performance and excellent long-term stability.

267 Setra Low range differential pressure transducers

The models 267 and 267MR are very low range transmitters for ranges as low as 0.1” WC with high overload capability of up to 700mb in either direction without damage. Both units offer a field configurable high level voltage or 4-20mA current output with the 267 offering the options of a 31/2 digit LCD display and static probe, making it ideal for Building Energy Management Systems with quick and easy installation directly on a duct, as well as a multi-range capability of six selectable ranges via D.I.P. switches., The 267MR has D.I.P. switches which gives a multi range capability allowing up to six selectable ranges.

5266 Setra very low range differential pressure transmitter

Gems 5266 low range pressure transmitter measures gauge or differential pressure by means of a stainless steel diaphragm, and capacitive sensor. The model 5266 incorporates an ASIC to provide a temperature compensated high level analogue out put over the temperature range -18 to +65°C. Mounted in a glass filled polyester, case with pipe fittings the 5266 can measure pressures in the range 100 – 5000 pascals., The 5266 utilises an all stainless steel microtig welded sensor. The tensioned stainless steel diaphragm and insulated stainless steel electrode, positioned close the diaphragm, form a variable capacitor. Positive pressure moves the diaphragm toward the electrode, increasing the capacitance. A decrease in pressure moves the diaphragm away from the electrode, decreasing, the capacitance. The change in capacitance is detected and converted to a linear DC electrical signal by Gems’ unique electronic circuit. The micro-tig welded tension sensor allows up to 69kPa overpressure (in either direction) with no damage to the unit. In addition, the sensor parts have thermally matched coefficients, which promote improved temperature performance and excellent long-term stability

5482 – Wet/Wet Differential Pressure Transducer

This series of miniature differential pressure transducers have a piezo-resistive sensor and a unique conductive seal that eliminates internal wire bonding thus enhancing reliability. Zero and full-scale adjustments are provided under the top cover. They are ideal for use in areas requiring exact pressure measurement, low hysteresis and long-term stability. For all applications where air, oil or water is to be, monitored. The unit is supplied with mounting bracket and integral 1 metre cable

TTPSD51 Trantech Electronic display differential pressure sensor

The Trantech TTPSD51 differential pressure sensor uses a diffused silicon sensor element to measure accurate differential pressure. The signal is processed by a post-processing circuit and converted into a, standard industrial electrical Milli-amp or Voltage analogue signal. The all-metal casing design, with a bright red LED digital display enables the product line to be used in a variety of industrial applications. The three-button design and menu make the product convenient to use and setup. A variety of process connections are available. The device electronics can rotate up to 330°, this guarantees the best screen viewing angle in different mounting positions.
