CALIBRATION & CUSTOM PRODUCTS

   
     

Temperature Transmitters are required to convert passive low level signal from temperature sensors (resistance from RTDs, millivolts from thermocouples into active and standard 4-20mA DC signals proportional to temperature, for transmitting over long distance, or for converting into an industry standard signal or where there is a likelihood of signal distortion or corruption by electromagnetic (EMI/EMC) interferences.
 

Model - UniCAL MASTER (MULTIFUNCTION CALIBRATOR)

 

UniCAL MASTER Calibrators are a part of LECTROTEK Uni-Series Microprocessor based calibrator products. The instruments are innovative in terms of compact size and cost-effective, yet full featured in terms of ease of use, programmability. It has full keyboard based operation for programming modes, changing steps and calibration.

Model - AC CALIBRATOR (Microprocessor-based AC Current Source)

 
 

 

FEATURES

Highly Accurate: 0.1% of AC current sourced
4-digit 7-segment LED display
Keyboard for operation and calibration
Handy unit, use in lab or at field
Mains powered, operates on 240V & 110V

Source function: generates precise AC current 0-5A to calibrate ammeters, current transducers, current indicators (CTs), single phase energy meters etc.

Manual or step modes of operation
Step function allows 10% steps change
 

AMPCAL generates upto 5 Amp AC output with an accuracy better than 0.1% for calibration of Current Transducers, secondary CTs, and all CT operated devices such as Current Trip Relays, Current Indicators, Analog/Digital Ammeters etc.

 

A 7-segment LED displays current generated, which is settable via keyboard, by manual decrement/increment mode or by step function, wherein current can be fed in steps by a single key press, for quick calibration
