Fairchild I/P transducers deliver high accuracy at very low pressures

11/01/2016

 

Rotork Fairchild has launched a new range of compact low pressure I/P (electro-pneumatic) transducers for instrument, analytical and scientific control applications.

Precise pressure control, where output pressures must be accurately held at low pressures down to 70 mBar (1 psi), has traditionally been a difficult task for industrial instrumentation. The new Rotork Fairchild T7500 range of transducers is specifically designed for these low pressure control systems with set point accuracy of 0.1%, even at pressures of less than 100 mBar.

T7500 transducers accept supply pressures between 1.3 and 2 Bar (20 and 30 psi) with mA or VDC control signals to deliver critical high accuracy output ranges of 0-350 mBar (0-5 psi) and 0-1 Bar (0-15 psi). Flow configurations of 85 l/m or 200 l/m suit a wide range of application requirements. In addition, the T7500 can be ordered with DIN plug, NPT conduit or terminal block electrical connections styles to suit assembly requirements.

Applications in test and medical equipment, leak detection equipment and other precise scientific areas are ideal for the T7500 transducers. The rugged cast aluminium construction and vibration resistant internal componentry is designed to withstand the rigors of both portable and stationary mounted equipment often found in medical and test situations.

As part of Rotork Instruments, Fairchild provides a complete range of regulators, boosters, I/P transducers and other products. Rotork Instruments can also provide fully approved switchboxes, positioners, solenoid valves and other actuation and severe service components to complete the automated flow control package.

New range of compact leak-free high pressure regulators

07/08/2012

 

Rotork Fairchild has launched a new range of compact high pressure pneumatic regulators for instrument and industrial control applications.

The new Rotork Fairchild range features patent pending improved valve seat sealing that eliminates the risk of media leakage often associated with conventional high pressure regulators. In addition, innovative diaphragm designs deliver superior accuracy and higher performance pressure regulation, especially with fluctuating supply pressures.

Constructed with 316 stainless steel bodies, the units are available as the HPD diaphragm design for pressures up to 413 Bar (6000 psi) and as the HPP piston design for even higher supply pressures.

 

The HPD design features high strength Inconel diaphragms as standard and will accurately regulate output pressures down to 1.66 Bar (25 psi).  It is available with the standard polymer valve seat for media temperatures up to 80°C and supply pressures up to 241 Bar (3500 psi). Optional higher performance valve seats are fitted for temperatures up to 260°C and a maximum supply pressure of 413 Bar (6000 psi). The all-stainless steel HPP piston design models will also handle temperatures up to 260°C and increase the supply pressure capability to 689 Bar (10,000 psi).

 

Both the HPD and HPP designs are available with 6mm (¼”) ports in either 2 or 4 port configurations and in multiple output pressure ranges.  Standard knobs can be replaced with tamper proof caps for high temperature and/or non-adjustment applications. Rotork Fairchild regulators can be mounted at the ports, the bottom surface or in panel mounted configurations.

Rotork Fairchild increases high pressure capacity of pneumatic regulator range

18/07/2013

 

Rotork Fairchild has increased the high pressure capacity of its compact leak-free pneumatic regulators for instrument and industrial control applications with the introduction of a new HPP range.

A companion to the recently announced HPD diaphragm style range of regulators, the new HPP (High Pressure Piston) range incorporates a piston design to manage supply pressures up to 413 Bar (6,000 psi) at temperatures up to 260ºC and deliver high output pressures between 207 Bar (3,000 psi) and 69 Bar (1,000 psi).
The HPP high pressure performance complements that of the HPD, which will also manage supply pressures up to 413 Bar (6,000 psi) and accurately regulate lower output pressures down to between 35 Bar (500 psi) and 1.66 Bar (25 psi).
Constructed with 316 stainless steel bodies, the HPP and HPD ranges feature patent pending improved valve seat sealing that eliminates the risk of media leakage often associated with conventional high pressure regulators.

Both ranges are available with 6mm (¼”) ports in either 2 or 4 port configurations and in multiple output pressure ranges. Standard knobs can be replaced with tamper proof caps for high temperature and/or non-adjustment applications. Rotork Fairchild regulators can be mounted at the ports, the bottom surface or in panel mounted configurations.
