These Temperature Transmitters are PC programmable or DIP Switch programmable. Some are isolated and accept input from various sensors such as RTD's, Thermocouples Voltages, Current, Resistance and Potentiometers. They have current outputs and we even have Temperature converters that have voltage outputs.

  • SparkFun Soil Moisture Sensor (with Screw Terminals)

    SparkFun Electronics

    The SparkFun Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The soil moisture sensor is pretty straightforward to use. The two large, exposed pads function as probes for the sensor, together acting as a variable resistor. The more water that is in the soil means the better the conductivity between the pads will be, resulting in a lower resistance and a higher SIG out. This version of the Soil Moisture Sensor includes a 3-pin screw pin terminal pre-soldered to the board for easy wiring and setup.

  • Speed Sensors

    McLAREN Applied Technologies

    DHE (Differential Hall Effect) sensors give an output when subjected to a changing magnetic field. The field is set up by a magnet inside the sensor body and changes when ferromagnetic teeth are passed beneath the sensor (no magnets are required in the target). To improve noise resistance, the sensor has two Hall effect elements and only responds to changes in magnetic field strength corresponding to tooth passing frequencies above 15Hz. As each tooth passes the sensor, the digital state of the output changes.

  • Voltage Probe

    KHZ43201 - Beijing KeHuan Century EMC Technology Co,.LTD

    The KHZ43201 voltage probe is a standard low resistance test probe, which meets the technical requirements for this product in the CISPR16-1 and CISPR14-1 test equipment. When measuring the interference voltage of the power grid, the artificial power supply network cannot be used at the load port, and sometimes it is necessary to use a voltage probe to measure the interference of the signal port, the load port, and the antenna port. The input impedance of the voltage probe to the ground wire is greater than 1.5KΩ, which can protect the input terminal of the receiver.

  • Acceleration Simulation Mode (ASM) Roller Set

    ASM-P-PLUS | VP 230047 - Maschinenbau Haldenwang GmbH & Co. KG.

    The ASM-P-PLUS roller set is used in test centres and is suitable for vehicles with a single driven axle. It was designed for the exact measurement of the exhaust gas behaviour of vehicles during their transient emission test and permits a driving resistance simulation for the exhaust gas tests ASM-5015 and ASM-2525 (Acceleration Simulation Mode) in accordance with the specifications BAR '97. The increased tractive force of its eddy current brake means that the ASM-P-PLUS is also suitable for power measurements at constant speed and constant tractive force.

  • Cable Length Meters

    PCE Instruments

    The cable length meters of PCE instruments provide various functions that can be useful in terms of measuring the length of cables or detecting cable breaks. Therefore the cable length meters function according to various measuring principles that will be described below. Using these devices enables determining cable lengths as well as the resistance and caliber of cables that are about to be laid or even already laid. Depending on the device that is being used, you can measure the length of cables to certain extends. Also the measuring ranges differ among the the devices.

  • Dielectric Constant (DC) and Dissipation Factor (DF)

    National Technical Systems

    Dielectric Constant is used to determine the ability of an insulator to store electrical energy. The dielectric constant is the ratio of the capacitance induced by two metallic plates with an insulator between them to the capacitance of the same plates with air or a vacuum between them. Dissipation factor is defined as the reciprocal of the ratio between the insulating materials capacitive reactance to its resistance at a specified frequency. It measures the inefficiency of an insulating material. If a material were to be used for strictly insulating purposes, it would be better to have a lower dielectric constant.
