Rheonics passes surveillance audits for ATEX & IECEx after relocation to new facility
Rheonics – Switzerland division recently relocated to a new facility in order to expand and streamline its operations.
The address for the new facility is as follows:
Rheonics GmbH
Klosterstrasse 19
8406, Winterthur
Switzerland
Updates on ATEX, IECEx certifications
After relocating to a new facility, Rheonics successfully passed the surveillance audits and is pleased to announce the release of its new ATEX & IECEx certifications. The certifications project started with the goal to better serve our worldwide customers, in broad range of industries. Rheonics GmbH facility has successfully implemented and put to practice a Quality Management System (QMS) along the requirements of ISO 80079-34 & ISO 9001.
As a long time manufacturer of fluid-sensing solutions, Rheonics is continuously identifying and designing new solutions and protections that our customers will trust in their hazardous and explosive locations.
ATEX & IECEx Compliance
Rheonics offers intrinsically safe sensors certified by ATEX and IECEx for use in hazardous environments. These sensors comply with the essential health and safety requirements relating to the design and construction of equipment and protective systems intended for use in potentially explosive atmospheres.
The intrinsically safe and explosion proof certifications held by Rheonics also allows for customization of an existing sensor, allowing our customers to avoid the time and costs associated with identifying and testing an alternative. Custom sensors can be provided for applications that require one unit up to thousands of units; with lead-times of weeks versus months.
Rheonics SRV & SRD are both ATEX and IECEx certified by TÜV Rheinland.
Certified Products
Rheonics SRV
Rheonics SRD- Wide range viscosity measurement (also density with SRD) with built in fluid temperature measurement
- Hermetically sealed, all 316L stainless steel wetted parts
- Stable and repeatable measurements in non-Newtonian fluids like paints and coatings
- Small form-factor for simple installation in existing flow lines and nozzle heads
- Easy integration with existing data acquisition systems using digital and analog data communication
- Smart self-detection of sensing element cleanliness, easy to clean and verify calibration
Sensor Description and Installation conditions
Rheonics SRV sensors are used to measure and control the viscosity of fluids, mainly under process conditions. Rheonics SRD sensors measure, in addition, fluid density as well as true dynamic and kinematic viscosity. Each sensor has a symmetric torsional resonator as its sensitive element. The effect of the fluid in which it is immersed on its resonant response – its resonant frequency and damping – is measured and interpreted by the electronics unit with which it is supplied.
Both of these devices, hereafter referred to collectively as “SR” sensors, are delivered in a version that is intrinsically safe. That means that as long as the sensors are installed and operated as specified in the EX manual, they are incapable of igniting explosive atmospheres in which they operate, provided they are operated within the envelope of parameters described in the EX manual.
Each Rheonics SR sensor is delivered paired with an electronics unit that both operates the sensor and transmits its measurement values over one of a variety of interfaces. When operating Rheonics SR sensors in a hazardous area, one or more Zener diode barriers must be installed between the Rheonics SR sensor and its electronics unit. This barrier serves to limit the amount of current and voltage available to the sensor in case of a fault in its electronics unit and/or within the sensor itself.
The Zener diode barriers themselves must be situated either outside of any hazardous zone, or in the zone specified by the manufacturers as safe for the barriers. The Rheonics SR sensor’s electronics unit must be situated outside the hazardous zone.
Area classifications
Zone 0: Zone 0 is an area in which an explosive atmosphere is present continuously for long periods of time or will frequently occur.
Zone 1: Zone 1 is an area in which an explosive atmosphere is likely to occur occasionally in normal operation. It may exist because of repair, maintenance operations, or leakage.
Zone 2: Zone 2 is a place in which an explosive atmosphere is not likely to occur in normal operation but, if it does occur, will persist for a short period only. These areas only become hazardous in case of an accident or some unusual operating condition.
