產品名稱：Advanced Signal Calibrator產品型號：ASC Series 生產廠商：AMETEK JOFRA(美國)產品簡介：The JOFRA ASC301 & ASC321 are portable process signal calibrators that provide the functionality and accuracy you expect from a laboratory calibration system, yet packed in a compact design that can fit into your tool box. These calibrators are easy to use and can be operated with one hａnd for field use.

詳細介紹

» Multi-function signal calibrator
With its robust custom housing, the ASC series is ideal for both field and workshop use. These calibrators are the process engineer’s best friend

» Documenting calibrator
The ASC321 provides a paperless calibration flow when combined with our wellknown JOFRACAL calibration software

» Input and output
RTD: 14 types, TC: 13 types, Current: 0-24 mA DC, Voltage: 0-20 VDC, Frequency: 0 to 10 Khz, Pulse: train output, Resistance: 5 to 4000 Ohm

» Simultaneous read-back
Including isolated read-back from deviceunder-test of mA, V and pressure

» Calibrate pressure
Add on a JOFRA APM pressure module to create a full-featured pressure calibrator that can perform a semi-automatic leak-test, pressure-switch calibration and more

» Calibrate temperature
Use the ASC together with a JOFRA temperature calibrator to add measurement channels for sensors or temperature switches

» Measure temperature
The ASC series can be used as a highaccuracy thermometer that works with RTDs and CvD equations, to obtain true
temperatures

» Optimal read out visability
Large ClearBrite™ display

» Fast RTD simulation
Quick enough to work with pulsed transmitters and PLCs

The JOFRA ASC301 & ASC321 are portable process signal calibrators that provide the functionality and accuracy you expect from a laboratory calibration system, yet packed in a compact design that can fit into your tool box. These calibrators are easy to use and can be operated with one
hａnd for field use.

The ASC321 is a full documenting calibrator, using predefined work orders from JOFRACAL. This ensures easy documentation and reduces the possibilities for errors when calibrating in the field.

The ASC series does more than just calibrate signals. Combined with the APM external pressure module or a JOFRA dry block calibrator, an ASC will calibrate pressure and temperature and, if used together with JOFRACAL, document it as well. For workshop use a DC power supply/charger is available.

The full numerical keypad, series of function keys and cursor keys, provide a simple and quick user interface. The new ClearBriteTM graphical display offers the best possible viewing.

The high accuracy of the ASC series has not been achieved on account of fragile measurements or source circuitries, both the ASC301 & ASC321 have fuseless protection ? this might save you a calibrator, as well as lowers your cost of ownership.
