Level Measurement & Control
AccuTrak AT100 and AT200 magnetostrictive level transmitters certified for IEC 61508 SIL 2 environments.
K-TEK has announced that its AccuTrak AT100 and AccuTrak AT200 high accuracy, magnetostrictive liquid level transmitters have been certified for operation in SIL 2 (Safety Integrity Level 2) environments.
The AccuTrak AT100 is a high accuracy, magnetostrictive level transmitter that can be directly inserted into the medium to be measured. The AccuTrak AT200 is an externally mounted, non-contact transmitter that can be attached to the K-TEK KM26 magnetic level gauge or other magnetic gauges to form a complete level measuring system. Both the AT100 and AT200 feature a modular, dual compartment design that separately houses wiring and electronics. Field-replaceable terminal components provide added flexibility and accuracy. AccuTrak transmitters can be used to measure clean or dirty fluids, and total level, interface level, or multiple levels from the same sensor. The transmitters provide accurate level measurements even with widely varying pressures and temperatures: up to 207 bar and 427°C.
Principle of operation
The transmitters operate using the magnetostrictive principle. A magnetic field around the wire in the transmitter causes a torsional stress wave that propagates at a known velocity. K-TEK’s patented, piezo ceramic sensor converts the mechanical torsion into a strong electrical return pulse that provides highly reliable measurements, even in harsh environments. The transmitter’s microprocessor-based electronics measure the elapsed time between start and return pulses, and convert the data into an accurate position measurement proportional to the level of the float.
The AccuTrak transmitters are housed in explosion-proof, power coated cast aluminium or 316L stainless steel, dual compartment enclosures. A variety of probe materials are available to accommodate many applications. The standard probe type is 316L stainless steel. Options include Alloy 20, Hastelloy C- 276, and PFAJacket over 316L stainless steel. The AccuTrak transmitters are FM Approved, CSA Certified, ATEX Certified, and GOST (Russia) Certified.
The AccuTrak magnetostrictive level transmitters are available with two-wire, intrinsically-safe, loop powered 4–20 mA signal outputs. Optionally available are HART protocol and Foundation Fieldbus for interoperability with a wide range of measurement and control systems. Level and temperature measurements are displayed locally via a built-in LCD display.
