Multiple identical data loggers are produced on sheet material and then separated to produce individual products for distribution to separate locations. A continuous roll of tape sheet material comprises a contiguous series of data loggers which each include a cover sheet, a transponder, a sensor, a power source (such as a battery), an antenna, a microprocessor, an adhesive layer and means to separate individual data logger elements from one another.

Data logger

A wireless transceiver includes a microprocessor for processing signals and communication circuitry coupled to the microprocessor. The communication circuitry includes input/output circuitry for receiving signals from a plurality of wireless devices over a wireless communication path, for providing the signals to the microprocessor, and for transmitting processed signals from the microprocessor to the plurality of wireless devices. The input/output circuitry of the transceiver includes a non-wireless connection coupling the wireless transceiver to a test and measurement device. The test and measurement device receives the processed signals from the microprocessor, processes the received signal and data and/or information encoded therein, and performs a predetermined response thereto.

Universal wireless transceiver

A measurement system includes a preexisting sensor, a transducer module installed in the pre-existing sensor including a memory storing information for identifying and operating the transducer, and a control device for communicating with the memory, the control device including a processor for automatically configuring the control device in response to data communicated from the memory and for collecting data from the pre-existing sensor. A method includes installing a transducer module into a preexisting sensor, and communicating between a memory of the transducer and a control device to automatically configure the control device in response to information for identifying and operating the transducer stored in the memory, and for collecting data from the pre-existing sensor.

Smart sensor

A thermoelectric connector module (C) is disclosed which comprises input () and output (E) connectors and contains signal conditioning circuitry (C). The input connectors () are interfaced with a hand-held detector (), and the output connectors (E) are connected to signal-utilising apparatus (). The module does not contain a battery but receives its power supply for the conditioning circuitry from the signal-utilising apparatus supplied via the output connectors (E). In this way, the module may be miniaturised, making it particularly suitable for mounting directly on a hand-held temperature detector or probe. Since the connector does not have to be opened for a battery replacement, it can be permanently hermetically sealed, providing resistance to dirt, dust, moisture, water and the like.

Two wire temperature transmitter

The combination in an instrument of a multimeter and an instrument having apparatus for determining a non-contact measurement of radiation perceived at a distance from a surface. The instrument may further have an apparatus for determining temperature of that surface by direct contact therewith. The non-contact apparatus may have optical sighting means and laser sighting means, and means for determining emissivity of the surface. Provision may be made for recording data, e.g. a data logger. Audio output may be provided in accordance with temperature determinations, and may include speech synthesizing. Conveniently, the instrument is adapted for holding in the hand, for example by a pistol-grip handle, and/or for mounting on a tripod as well as a threaded connection with a wrist strap or a tripod. Temperatures derived respectively from infrared radiation, and from direct contact, have separate displays. The multimeter and the temperature instrument may have means for their control by vocal command.

Pyrometer multimeter

A thermoelectric cold junction compensator connector module, for use with a thermoelectric device such as a thermistor, thermocouple, or resistance-temperature device, has within a housing a cold junction compensator circuit which has means for linearization of voltage output of the circuit relative to input to the circuit. Preferably the circuit also includes potentiometer means for adjustment of at least one parameter of the circuit, and means for adjustment of its voltage output to correspond to degrees Centigrade and degrees Fahrenheit. In a preferred form there are included within the housing a pair of input terminals shielded by ferrite material against stray electromagnetic induction signals, a printed circuit board which comprises a cold junction compensation circuit, a signal linearization circuit, a converter/amplifier circuit, and a circuit for selectively providing a degree Centigrade and degree Fahrenheit output, a battery power supply, and a battery status indicator with means for bringing it into and out of operation, a plurality of potentiometers for preliminary setting up of the circuits, an on-off switching means for the powered circuits, and output terminal means for connection to, for example, a voltmeter or a voltage recording device. The compact body may have a base portion on which the circuits and other items are mounted, and one or more removable cover portions securable on the base portion. Further, a thermocouple voltage-to-analog connector is in the form of a compact hand-held module which contains all the components and power supplies for converting an input of thermocouple output voltage to a linear and cold-junction-compensated analog output. A particularly advantageous feature is that an on-board analog-to-digital converter only calculates and provides the linearity correction, necessary for the specific thermocouple at a specific temperature, in the form of a pulse width modulation signal output, so that about 95% of the analog output is derived from the output of a thermocouple amplifier and temperature sensor, and only 5% of the remaining signal is derived from the on-board micro-processor.
