Reliable Temperature Measurement in Hazardous Areas
Jan 02 2009
Nulectrohms (UK), a Roxspur Measurement & Controls company, manufacture intrinsically safe, Multiple Resistance Thermometers (MRTs) of high accuracy for true averaging temperature measurement in a wide range of applications. These MRTS include a stable element design that can not sag and alter average weighting. The thermometers are suitable for use in harsh and corrosive environments and compatible with industry-standard level gauges. Additonally, Roxspur’s MRTs offer true-averaging copper or platinised copper elements, with element resistance of 100 ohm at 25oC or 0oC.
The sheath, made of stainless steel or nylon, contains a number of elements of different lengths all starting from the bottom of the sheath. The construction of the sheath and elements is such that the elements retain their dimensional properties under vibration and environmental changes frequently encountered in many installations. True 3-wire compensations is possible as the element design is such that the start and finish of each element is at the bottom of the assembly,making all lead lengths equal. All elements are calibrated at 3 temperatures: high, low and mid point ‘ballast’ for extended accuracy. The maximum number of averaging elements is 12, plus where required a bottom spot element can be added. The stainless steel MRT is certified to conform to the ATEX directive and the CENELEC EN50014, 50020 standards. Nulectrohms are market leaders in multi-element thermometers used in a wide range of applications including storage of hydrocarbons. The high accuracy of the elements make the Nulectrohms MRT an integral part of tank gauging systems used for custody transfer and inventory control applications.
