Rotronic Cleanroom Panel for Differential Pressure


T


Hydra-Cell Excels in Filter Pressing


H


ydra-Cell pumps are finding favour in filter press applications for both chamber feeding at high pressure and for fuelling the cloth washing operation. Acid washing of filter cloths is used extensively in metal finishing. A low pressure acid solution is recirculated through the filter press to partially dissolve and dislodge the solid particles that ‘blind’ the cloths. Particles in this aggressive recirculating solution can cause catastrophic damage to pumps with dynamic seals but being seal-less by design, Hydra-Cell pumps are reported to be unaffected and give many years of trouble-free service. Now, with the addition of the Q Series high horsepower quintuplex pumps, the Hydra-Cell range covers virtually all flow requirements for this application.


In the cold pressing of oils for pharmaceuticals and cosmetics manufacture, the filtered oil must be clear and polished with no air entrainment.

he Rotronic CRP5 panel meets monitoring and control requirements for cleanroom environments; with FDA 21CFR part 11 compliance and validated to GAMP5 Directives. It provides precise measurements of differential pressure using a diaphragm sensor, temperature and humidity.


food industry, laboratories and together with


The CRP5 has been designed for installation in cleanrooms in hospitals, pharmaceutical facilities, electronics production and assembly areas,


wherever small differences in pressure are critical.


The wall panel has a tough, wipe clean glass front plate which is highly resistant to chemicals; optical buttons can be operated using protective gloves.


The option of a


magnetically mounted humidity and temperature probe which is removable in seconds provides for efficient and effective cleaning


Up to six measurement values can be shown on the graphical colour display. There are visual alarm indicators for defined values that have been breached, faults and alerts


With its analogue and digital interfaces it is easy to integrate into any monitoring system; there are six relays. Configuration is easy using the four optical buttons and Rotronic HW4 software, or via Modbus RTU/TCP


Any Rotronic HygroClip2 interchangeable temperature and humidity probe may be connected for measurement at a specific point in the cleanroom. Door monitoring is via contacts.


The operating ranges are wide: up to 500 Pa, -100…200 °C (probe dependent) and 0…100 %rh The CRP5 panel sensors are easy to calibrate away from the cleanroom.

Contelec’s new absolute single-turn/multi-


turn contactless sensor has improved design N


ow available from Variohm EuroSensor, Contelec’s recently announced Vert-X 37MT Hall Effect encoder combines a 16-bit single-turn angle resolution with 16-bit multi-turn count (65536 turns)


for unconstrained position feedback. Unlike conventional single-turn + multi-turn designs, the Swiss sensor specialists has employed a novel magnetic field measurement technique where no gearing is used or battery required – with the number of turns counted and saved in non-volatile memory that is powered by stored energy from shaft rotation. In this way absolute position is not lost during power down and is immediately available on power-up. The 24V DC CANopen interfaced encoder’s impressive specifications include independent linearity of +/- 0.1% (360 ) with hysteresis to 0.1º and maximum repeatability to 0.1º. The Vert-X 37MT’s speed capability of 3000 rpm speed capability suits servo motor feedback, and with 360 million minimum movements specified, long life is assured. Aimed at heavy duty applications such as construction machinery or agricultural equipment, the highly durable IP68 sealed design includes duplex bearings and all stainless steel external hardware to provide maximum resilience to adverse environmental conditions. Its industry standard DS-406 CANopen device profile, contactless design, and high axial & radial load capability all contribute to straightforward installation, long working life and high-reliability position sensing. The encoder’s nominal housing dimensions are 55mm long x 36.5 mm diameter.


The standard


version includes a size 13 servo mount with a 10 mm diameter slotted and flattened D-shaft and M12- m connector interfacing. Alternative multi-turn options are 2, 8 or 12 turns, or custom configured for the application.

licat Scientific has added two new families of electronic pressure controllers specifically for high volume original equipment manufacture. The EPC family with single proportional valves, and EPCD family with dual valves, provide customised pressure control in embedded systems. The small footprint instruments respond quickly to upstream fluctuations to provide fast, accurate control of pressure in an economical,


package. Alicat offers a choice of valves,


easy-to-integrate valve


orifices and process connections to fit customer specifications. EPC instruments are ideal for use in OEM gas chromatographs, fluidics dispensing for flow cytometry, and anywhere responsive pressure control is needed.


EPC and EPCD instruments have a 100 ms control response to still upstream pressure fluctuations in real time. NIST-traceable accuracy is 0.25 % full- scale. The EPC family’s single proportional valve provides stable control of pressure in flowing applications, such as maintaining flow of carrier gas through the sample injection point in gas chromatographs.
