Sealing materials improve asset reliability


T


hermiculite sealing technology was developed by Flexitallic to provide a successful seal across the widest


spectrum of chemical processing technologies. Chemically an inorganic silicate, Thermiculite possesses outstanding resistance to extremes of both chemical media and temperature; capable of sealing at temperatures ranging from cryogenics to in excess of 1000˚C - even in oxidising environments. The ability of Thermiculite to encompass such media and process extremes lies in its basic chemical make up; structure and availability in different gasket styles. Expansion of the crystal structure and packing optimisation of the resulting silicate plates ensures gas tight sealing under extreme process conditions. Recent testing has proven the materials ability to seal to extremely low leak rates; thousands of times tighter than the requirements of Germany’s air quality standard (TA Luft VDI 2440).


Thermiculite technology is available as soft cut gaskets for low pressure sealing applications and semi-metallic products for intermediate, high pressure or cycling applications. Thermiculite offers a single solution replacing the need for a range of sealing products based on a variety of other materials’ technologies. Real cost savings with respect to inventory reduction, emissions compliance, increased gasket life and reduced potential for misapplication are now within every process engineers’ grasp.

Underpinning its reliability in continuous process environments, the Type 8175 integrates a range of fail-safe features, including signal loss, power supply failure, and level or temperature alarms, which can be activated with an adjustable time delay. In addition, a range of filter functions control the return echoes and automatically eliminate all

urkert’s Ultrasonic Level Transmitter Type 8175 provides continuous level measurement at distances up to 10-metres. Integrating an ultrasonic sensor and a transducer with a large 8-digit multi-language display in a splash-proof IP65 or immersion-proof IP67 housing, the Type 8175 offers users a teach-In function for easy commissioning, and also delivers low total cost of ownership.


Designed for use in water treatment, pharmaceutical, food and other hygiene- based industries, the 8175 is a non-contact filling level transmitter that can be used in both open and closed vessels. Simple to use, with its menu-guided operation and 8- digit alphanumeric display, the Type 8175 delivers fast and easy commissioning with its integrated Teach-In and Simulation functions. These allow different tank shapes (cylindrical, cubic, spherical) to be easily programmed via fixed default shapes, or at complex tank shapes step- by- step. Importantly, the simulation functions allow the system to be tested under dry-run conditions, and the resulting measured value can be shown as a level, a distance (in cm, m, inch or feet), or direct, as a volume (litre, m3 gal or US gal).

interference due to elements of the vessel. The 8175 transmitter is powered with 18-32 VDC (optionally 115/230 VAC) and features a three-wire 4-20 mA output for direct control of a continuous control valve, interface to a PLC, or for monitoring. Two optional 3A relays can be also configured as alarms or latched for automatic fill or empty operations. Burkert offers the 8175 Ultrasonic Level


Transmitter together with process control valves as a complete, easy to control system. The transmitter can be used with Burkert Type 6213 solenoid valves, Type 2030 diaphragm valves, Type 2712 continuous TopControl System, Burkert 8644 valve islands and third party vendor PLCs in one totally integrated, easy to commission system. ■
