Patent number: 8801271Abstract: A calibration apparatus for temperature probes comprising an elongate calibration chamber (1) with an opening (2) for receiving an insert (3) that has passages (4) for receiving temperature probes (6), and wherein the chamber (1) has several heat energy elements (-11) that are controlled by temperature probes (12-14). In the insert as such one or more external probes (7) are provided, each of which has one or more temperature sensors to the effect that at least two sensors (19, 20 or 15, 17) are provided at respective dissimilar distances to an end of the insert (3). The latter sensors are connected to electronic regulation (20, 23) and measurement units (21, 24) for regulating the supply of power to the heat energy elements.Type: GrantFiled: October 27, 2008Date of Patent: August 12, 2014Assignee: Ametek Denmark A/SInventors: Jan Haakon Harslund, Folke Galsgaard

Temperature calibration device, a calibrator block, and a method for calibrating a temperature probe
Patent number: 8721173Abstract: A temperature calibration device 1, comprising a calibrator block 3 having a cavity 4 and one or more heating elements and at least one temperature sensor being thermally coupled to the calibrator block 3, and where the heating elements and the temperature sensor is connected to a control system being adapted for controlling the temperature of the calibrator block 3, and where the calibrator block 3, at least partly, is surrounded by thermally insulating material 5. A number of channels 9 are arranged in the calibrator block 3 or the insulation material 5, and being connected to a gas supply 6, and where the control system is adapted for activating or deactivating the gas supply.Type: GrantFiled: February 19, 2009Date of Patent: May 13, 2014Assignee: Ametek Denmark A/SInventors: Jan Haakon Harslund, Jørgen Reinholdt Larsen, Folke Galsgaard -
Patent number: 8342742Abstract: The invention relates to a temperature calibrating system (1) comprising a thermo siphon, a heat pipe or an equivalent (2) connected between a cooling unit (4) and a temperature calibration unit (3), where the system (1) further comprises an external chamber (8) connected to the heat pipe/thermo siphon or equivalent (2) for controlling the thermal conductivity between the two units and where the temperature of the external chamber (8) is held at a certain temperature, for example ambient temperature or a temperature controlled by external means. The external chamber (8) can be connected to the heat pipe/thermo siphon (2) via a conduit (9) which connection point is placed above liquid level at a evaporating end of the heat pipe/thermo siphon (2) and in that the external chamber (8) is arranged below the connection between the conduit (9) and the heat pipe/thermo siphon (2).Type: GrantFiled: September 18, 2007Date of Patent: January 1, 2013Assignee: Ametek Denmark A/SInventors: Jan Haakon Harslund, Jørgen Reinholdt Larsen, Folke Galsgaard

Patent number: 7541817Abstract: A method of diagnosing corrosion risk of a buried pipe due to DC stray currents and/or AC voltages induced in soil employs a metal probe including a first, exposed part having a first specific resistivity, and a second, sealed reference part having a second specific resistivity. The probe is buried in the soil, and the AC current and voltage between the pipe and the probe are measured, from which the spread resistance is determined. The resistances of the first and second probe parts are determined by respectively passing first and second excitation currents through the first and second probe parts and measuring the voltages across them. The resistance measurements are stored, and the steps are repeated periodically. The corrosion of the first probe part is determined from the measurements according to an algorithm, and the pipe corrosion risk is diagnosed from an empirical combination of the corrosion of the first probe part, the spread resistance, and the AC voltage measured.Type: GrantFiled: March 1, 2005Date of Patent: June 2, 2009Assignee: Metricorr APSInventors: Lars V. Nielsen, Folke Galsgaard
