Weldable Resistance Thermometer Type TP13 Hengesbach

The Weldable Resistance Thermometers Type TP13 and TP15 are high-performance, robust and all-purpose devices
for demanding applications within the temperature measuring. The PT100 sensor is designed standardly in accuracy class A acc. to EN 60751. The measurement inserts consist of single- or double PT100 which are changeable. The use of measurement inserts has to be adjusted to the needs for temperature, length, flexibility, vibration-proofness and measuring accuracy. For control processes tapered sensor tips with extra short half-life-times are deliverable. Safety and profitability aspects advise constructions with protective tubes in case of a possibly necessary change of the probes, so that replacements can be carried out quickly and comfortably, without decommissioning the plant or draining the tanks.

Furthermore protective tubes guarantee the resistiveness against mechanical stress and chemical attacks, also to be designed for a quick response time. For sensitive measuring points, like e.g. stipulated in the food and pharmaceutical industry, suitable hygienic designs and versions are available. Cleaning with all in these industries common media (CIP etc.) is possible. The construction in protection class IP67 guarantees reliability for closeness and long durability even under extreme operating conditions. For measurement transmission purposes programmable transmitter 4...20 mA, in versions HART or Profibus PA, can be installed. Notably the QUICK TEMP-product family is recommendable for calibration obligatory measurement points.
