Flexible Rope-Type Current Probe
RCT1A and RCT5A
These probes have great bandwidth ensuring accurate measurement even with harmonically distorted wave shapes. For all RCT1A/RCT models, a NIST, NAVLAP, NPL (UKAS) factory traceable calibration certificate and certificate of conformance is supplied. UL/CSA approved materials are used throughout. Three phase and single phase flexible AC current sensors (rope sensors) are available for fast installation in confined spaces, eliminating the need for Electrical Supply Shutdown. Available outputs are 1A @ 2.5VA and 5A @ 0.5VA, this means long cable lengths from current sensor to signal conditioner allow these low VA ratings to be used, even when feeder cable to energy meter distances are large (up to 98 feet / 30 meters)

Flexible Current Sensor Probe
CTA
The CTA current sensors convert ac current to an isolated 0-5A current with available ranges from 100A to 10,000A. Because the current sensors are flexible split core, installation is possible without shutting down the LV electrical supply, avoiding expensive down-time costs. Typical applications are retrospective energy monitoring in factories, offices buildings, process control data logging systems, where power, energy and current monitoring is important. Typical applications are factories, offices buildings, ac/dc VFD drives, welding, power conversion and power distribution. For all CTA current sensor models, a NIST/NPL (UKAS) traceable calibration certificate and certificate of conformance is supplied. All CTA sensors use UL94V0 or CSA approved materials. The CTA flexible current sensors are suited to permanent or semi permanent installation. The coil sensor is durable, lightweight, flexible and will easily clip-around a power cable. The 5A output from the CTA current sensor connects direct to installed metering, rotary metering or current transducers.

Multifunction Calibrator 15 ppm Basic Accuracy
MC142
Multifunction calibrator MC142 is a precision voltage, current and power calibration source serving as a measurement standard in calibration laboratories and production lines; where verification of electrical measurement equipment & sensors is required. It can be used for calibration and adjustment of meters measuring voltage, current, power, resistance, capacitance and frequency. Internal harmonic and non-harmonic signals make it possible to test electrical performance of meters using signals with various crest factors. Frequency modes enable selection of frequency, amplitude and duty cycle of the output signal. These are suitable for basic calibration of digital and analog oscilloscopes along with transient recorders. The calibrator is equipped to measure temperature with TC and RTD temperature sensors. Its built-in multimeter can be used independently or simultaneously with the calibrator output. Testing of transducers of various types, regulators and sensors can be performed, without the necessity to use any other measuring instrument.

Phase Meter
SD1000
The SD1000 phase meter offers superb accuracy with a wide range of signal conditions. Conventional phase meters are easily upset when small levels of noise and distortion are present - the result is often unstable and incorrect phase readings. The SD1000 overcomes this by using Discrete Fourier Analysis (DFT), this process rejects any noise and distortion without the need for tracking filters.

Power Cell Power Transducers for Wide Ranging AC/DC Loads
PH-3A and PH-1000
You can know the load on an electric motor by measuring the electric current going to the motor (Amps). But, this is not the best way to do it since a lightly-loaded motor doesn't use the electricity very efficiently. (In technical terms, the power factor is low.)A better way to know the load is to measure the motor power. (Power is measured in Horsepower or Watts.) Motor power gives you a straight line so it works well even when the motor is lightly loaded.The Power Sensors that we make measure the motor load (Horsepower or Watts) and send a signal to meters or computers. The operator can see what the status is on the meter or, the computer can make decisions.

PC Controlled Bench Top Power Analyzer
PA2100
The PA2100 is a PC controlled bench top power analyzer, allowing several electrical power measurements to be taken simultaneously during testing - from just one set of input connections. The PA2100's power measurement ability is a must in research and development, manufacturing and required for certification and traceability of manufactured goods. In addition to power measurements, apparent power (VA), harmonics, voltage, current, power factor can all be viewed and stored with ease. The PA2100 wattmeter simply connects between the ac supply and the load, various current transformer options allow measurement with any size of current from 10mA to 10000A. Typical watt meter applications include appliance testing; microwave ovens, electric stoves, heating, air conditioning, TVs, monitors, computers, electronic lighting, fans and motor controllers. Powertek wattmeters are equipped with 4mm/banana safety terminals along with optional "breakout" boxes and clamp current probes for fast and safe measurement.
