Pressure sensors New from OEM Automatic is the P3276 pressure sensor range from Tecsis. Its wide pressure range consists of 38 EN ranges in positive and negative gauge, vacuum and absolute, from -1 to +2500bar. It also has a 4-20mA or 0-10V output (with others available); G1/2” process connection; stainless steel construction; accuracy of 0.5% or 0.25%; and adjustable zero point and full scale ±5%. Applications range from high pressure hydraulic industrial appli- cations to low pressure laboratory/phar- maceutical or process control systems. OEM Automatic

Bellows valve for fluid separation
Valve booster enables precise control
New from Samson Controls is a booster to eliminate the trial and error procedures associated with the fine-tuning of control valves. Due to its precisely manufactured bypass restriction, the booster can be adjusted exactly and lead- sealed in this set-up.
Being pressure balanced, this provides a stable output, even under fluctuating pressure condi- tions. In addition, signal pressure is transmitted with a defined hysteresis, without loss (gain 1:1) and emits minimal noise. When used in combination with a positioner, the booster allows control valves with large pneumatic actuators to be con- trolled quickly and precisely. Samson Controls T: 01737 766391

For hygienic applications, Bürkert has introduced the compact stainless steel FDA-approved Type 2080 2/2-way valve which integrates a PTFE bellows. Designed for fluid separation tasks with gases and liquids in the range from Vacuum to 8-bar, and temperatures (ambient) to +90°C, this allows flexible configuration with different types of armatures and customised port connections. The valve itself comprises a pneumatically operated piston actuator with return spring, a stain- less steel body and a PTFE bellows, which provides separation of the medium. The pneumatic actuator is servo assisted by a pilot valve, a valve block, or similar, for faster, more precise response. Furthermore, position detection is provided by reed contacts in a two-wire system that can extend to 3m. The option of a three position actuator giving high and low flow rates means this valve is ideally suited to high accuracy batching applications. The valve offers optional flange connection – other options are Manifold pattern, tube weld and G 3/8 threaded ports – for maxi- mum safeguarding of processes, and has internal contours that are simple to clean (CIP and SIP). In addition, when used in the upright position, the 2080 offers the advantage of self-draining operation. This is available as a standalone unit or as part of system combined with support components such as the Type 6012 pilot valve, the Type 8041 flow sensor, and the Type 8645 valve islands. Bürkert
