2553A DC Calibrator
Precision DC Cailibrator Model 2553A is powered by Yokogawa's highly accurate and precise voltage and current generation technology, capable of generating up to +/- 32 V DC and +/-120 mADC with high reliability and high stability. In addition to calibrating voltage and current meters, the 2553A is also capable of calibrating temperature meters and controllers which measure temperature by thermocouple or Resistance Temperature Detector (RTD). Output value is adjustable intuitively by dials for each digit.

The 2553A Precision DC Calibrator, like our other Calibrators and Sources, offers users the simple operation and reliability they have come to trust from Yokogawa.

APPLICATION:

# Calibrating and testing analog meters
The 2553A can calibrate and test analog meters up to +/-32 V voltage and +/-120 mA current. The strong click from the dial enables easy adjustment of output value without actually looking at the front panel.

# Calibrating and testing temperature controllers
The 2553A can calibrate and test temperature controllers and data loggers using thermocouple and RTD. It provides 10 types of thermocouples regulated in IEC. By setting temperature value, it generates thermocouple electromotive power and calibrates temperature controllers.

# Calibrating and testing sensor transformers
The 2553A calibrates the transformers and transmitters for pressure, volume flow, and temperature. It also calibrates transformers for analytical instruments such as pH, ORP, EC, and DO meters. High voltage output accuracy of 2553A will enable support for transformers which require higher accuracy. 2553A will come in use even in developing and testing transformers.

# Simulating the two wire transmitters
In 30 mA range, the 2553A can sink the current. For example, by sinking the current from the distributors, it can simulate the two wire transmitters which output 4 to 20 mA signals.
