JOFRA ASC300 MULTI SIGNAL PROCESS CALIBRATOR - - -
Cover all your needs for a process signal calibration with superior accuracy. |
 |
The ASC300 is substantial enough to cover all your needs for a process signal calibrator with superior accuracy and compact enough to fit into your tool box and operate with one hand for easy field calibration. The ASC300 can change your entire calibration regimen for signal, pressure, and temperature. You can combine this versatile calibrator with the JOFRA APM external pressure modules or a JOFRA dry-block calibrator to meet your calibration needs. |
Multi-function signal calibrator with high accuracy. Ideal for both field and maintenance shop use.
Input and output
- RTD: 14 different types
- TC: 13 different types
- Current 0-24 mA DC
- Voltage 0-20 V DC
- Frequency 0 to 10 Khz
- Pulse train output
- Resistance 5 to 4000 Ohm
High level of protection with full fuseless protection to 240 VAC.
Simultaneous read-back including isolated read-back from device-under-test of mA, V, and pressure.
Fast RTD simulation this feature is fast enough to work with all pulsed transmitters.
Calibrate pressure at varying reference levels using external pressure modules with accuracies up to 0.01% F.S.
Calibrate temperature using JOFRA dry-block calibrators with accuracies up to 0.04°C / 0.07°F.
Multi-information graphical display for simultaneousreading of both output and read-back.
Full remote control of all functions with the help of simple ASCII commands. |
Simultaneous input and output
The JOFRA ASC300 offers simutaneous input and output. This means that you can calibrate and adjust a temperature transmitter on the table with no other necessary instruments. Output the sensor signal and input the mA from the transmitter. If you select mA Loop the JOFRA ASC300 will also supply the 24 VDC for the loop. In the display you will see both your output temperature and the return mA from the transmitter. Enter the zero and full scale values and you can make quick 25% steps or go direct to zero or full span values. The JOFRA ASC300 has dedicated keys for this operation so adjustment on the transmitter is made easier. |
Temperature reading at reference level
The JOFRA ASC300 offers the possibility to charaterize an RTD sensor. Use this feature to add a missing special curve or to characterize a reference RTD. If you choose a reference RTD from the JOFRA STS100 series of high accurate and stable temperature sensors, they will be delivered with a traceable calibration certificate including the neccessary Van Dusen coefficients. Enter the figures into the JOFRA ASC300 and you have a temperature reference. Complement this with a JOFRA dry-block temperature calibrator and your JOFRA ASC300 becomes the heart of your portable calibration lab. |
JOFRA APM Advanced Pressure Module
The APM series of pressure modules offer the flexibility to perform pressure calibrations with the ASC300. The pressure modules are compatible with the JOFRA AMC900 bench top calibration system and the JOFRA ASC300 handheld multi-function calibrator. Independent of the engineering unit of the module you can change units on the ASC300 (11 different engineering units) at any time. These rugged modules are engineered for both field and laboratory use. They are ready to use with the JOFRA calibrators and the protocol allows for immediate recognition and use of the module once it is plugged into the calibrator. All calibration data are stored in the modules. You only need to maintain the traceability of the modules - not the indicator, and, you can always add more as your needs change. For use out-of-the-box any where in the world all units are supplied with a 1/4 in. NPT and a BSP female adapter. |
