  • 7005 - Loop Calibrator (MET VA) The 7005 is a micro-processor based handheld process control instrument for voltage and current loop calibration and simulation. It can operate in three modes: a) Loop current/voltage Source (transmitter simulation and loop supply simulation) b) Sink of loop current (transmitter simulation) c) Measurement of loop current/voltage (loop indicator simulation).

  • LC-110H - Precision Current Loop Calibrator With Hart Communications The Martel LC-110 and LC-110H are mA (loop) calibrators designed to take the loop calibrator class to the next level. The new LC-110 series feature a user friendly interface with dedicated buttons and a rotary encoder (Quick-Set Knob). This combination drastically reduces the time it takes to measure, simulate, or source both voltage and current and power up a loop. The rugged ABS plastic case is contoured to easily fit a technician's hand and the large back lit graphics LCD is best in class. The LC-110H differs from the standard LC-110 in that it incorporates HART communications and supports a select set of the HART universal and common practice commands. This unique feature allows the LC-110H to be used as both a loop calibrator and communication tool.

  • Open Loop Current Sensors Open loop current sensors measure DC and AC currents and provide electrical isolation between the circuit being measured and the output of the sensor. Typically, open loop current sensors cost less than closed loop sensors. They are preferred in battery powered circuits due to their low operating power requirements.

  • Ae30-300 - H-field active loop antenna The principle of operation is that an RF voltage appears across the terminals of a loop when it is placed in an electromagnetic field. This voltage is proportional to frequency for a given field strength. Therefore at Very Low Frequencies, the voltage is very small, and requires greater amplification.
