PRODUCT FEATURES 1.1 Heavy-duty mineral insulated measuring inserts The OPTITEMP TR/TC 100 measuring inserts are intended for installation in thermometer assemblies and are made using mineral insulated mantle cable. They feature flexibility, superior insulation resistance and a high degree of vibration resistance. The TR 100 version contains a Pt 100 RTD with a characteristic curve according to DIN EN 60751. The TC 100 version features a thermocouple according to DIN EN 60584. Thermocouple measuring inserts come in type "K" or "J", other types are available on request. © Measuring insert...

PRODUCT FEATURES All three variants (with terminal block, with flying wire ends, with head-mounted transmitter] are also available as intrinsically safe measuring inserts. The ATEX marking is: The intrinsically safe measuring inserts always have a sheath diameter of 6 mm / 0.24". The following options are available: • Sensor: 1 x Pt 100 RTD (wire-wound, ceramic) or 1 x thermocouple ("K" or "J"] • Tolerance class A (Pt 100) or 1 (thermocouple] The measuring insert with a resistance thermometer features a temperature-sensitive sensor made from a platinum RTD, whose value at 0 C / +32 F is 100...

DPRODUCT FEATURES The thermocouple features two electric conductors made from different metals, connected at one end. Each free end is connected to a compensation cable which is then connected to a millivolt meter. This circuitry forms a "thermal circuit". The point at which the two electric conductors connect is called the measuring point and the point at which the compensation cables connect to the conductors of the millivolt meter is called the cold junction. If the measuring point of this thermal circuit is heated up, a small electrical voltage (thermal voltage) can be measured. If,...

2.3 Permissible flow speed The maximum permissible flow speed forthe measuring insert depends on its immersion depth and on the density of the product. The greater the immersion depth and the higher the density, If the measuring insert is used in the thermowell, the flow speed is irrelevant. If, however, the flow goes against an unprotected measuring insert, its load must be calculated individually. If this isthe case, the manufacturer will offer further support. 2A Permissible operating pressure The maximum permissible load of the measuring inserts through the static operating pressure The...

The operator himself bears the sole responsibility for the intended use of the measuring device regarding the suitability and the corrosion resistance of the used materials against the measured fluid. The manufacturer is not liable for any damage resulting from improper use or use for other than the intended purpose. Intended use is when the measuring insert is operated in a suitable thermometer assembly allowing for incorporation of replaceable measuring inserts. In every instance, the sheath length must be adapted to the thermowell. For more information about adjusting the thermowell and...
