Core functional highlights

1. High precision measurement and simulation:

• Multi parameter measurement:Accurately measure various industrial process signals such as DC voltage (mV/V), DC current (mA), resistance (Ω), frequency (Hz), thermocouple (TC), thermistor (RTD), etc.

• Multi parameter simulation:High precision output of DC voltage (mV/V), DC current (mA), resistance (Ω), frequency (Hz), thermocouple (mV), and thermistor (Ω) signals for exciting or testing the tested equipment.

• highAccuracy:Provide industry supportThe measurement and output accuracy (usually within the range of 0.01% to 0.02%) ensures the reliability of the calibration results.

• 24 bit ADC/DAC:High resolution analog-to-digital converters provide precise measurements and stable outputs.

2. Circuit power supply and measurement:

• Built in circuit power supply:It can provide working power (usually 24V DC) for 2-wire (4-20mA) transmitters and accurately measure the current signal output by the transmitter. This is the function of on-site debugging and calibration of the transmitter.

• Current measurement:Measure the current value of the circuit without interruption while providing power to the circuit.

3. Powerful HART communication function:

• Read/Write:Read the process variables (PV), range, units, labels, descriptors, dates, and other parameters of the transmitter; Write configuration parameters such as range, unit, label, damping time, etc.

• Calibration:Perform zero and range adjustment (Trim) to fine tune the sensor.

• Loop testing:Test whether HART communication is normal without interrupting the circuit.

• Diagnosis:Access the diagnostic information of the transmitter to assist in troubleshooting.

• Integrated HART modem:One of the core advantages of UPS4E is its built-in HART modem.

• HART master device:Can be used as a HART master device to directly communicate bidirectionally with smart transmitters that support the HART protocol.

• Rich functionality:

• Simplified maintenance of smart meters:Greatly simplifies the configuration, calibration, and maintenance process of HART smart instruments, without the need to carry additional HART controllers.

4. Dual channel operation (some models/functions):

• Some UPS4E models or supported through specific accessories/modesdual-channelOperation.

• Typical applications:One channel is used for measuring/simulating process signals (such as mA output), while the other channel is used for simultaneously measuring/simulating auxiliary signals (such as RTD resistance), which is very efficient for calibrating temperature transmitters and other devices that require synchronous operation of the main variable and sensor inputs.

5. Pressure measurement (in conjunction with Druck pressure module):

• UPS4E is typically designed with modular interfaces.

• Connect pressure module:Seamless connection to Druck's series of high-precision pressure modules (such as PACE/CPM/CPH series).

• Pressure measurement/simulation:Through connected modules, precise measurement of pressure parameters can be achieved (reading pressure sensor/transmitter output) or simulation (outputting pressure signals to pressure indicators/recorders/controllers). This makes it a core component of a comprehensive pressure calibration solution.

6. User friendliness and efficiency improvement:

• Large backlit display screen:Clearly display measurement values, output values, units, functional status, and HART parameter information.

• Intuitive menu navigation:Clear functional organization, simple operational logic, easy to learn and use.

• Quick setup:Provide convenient functions such as percentage stepping, up and down key fine-tuning, and quick zeroing to accelerate calibration speed.

• Data recording:Some models support data recording function, storing calibration or testing data for easy viewing or exporting of reports in the future.

7. Durable and Safe:

• Industrial grade design:The sturdy shell design can withstand harsh on-site environments such as dust, moisture, and vibration.

• High protection level:Usually reaching IP54 or higher, providing good dust and water resistance.

• Security certification:Compliant with relevant international safety standards (such as CE, ATEX/IECEx - specific models suitable for hazardous areas).

• Long endurance battery:Large capacity rechargeable batteries provide long-term operational support.

• Overload protection:The input and output ports have protective functions to prevent damage caused by accidental wiring errors.

Typical application scenarios

• Calibrate pressure, temperature, liquid level, and flow transmitters (4-20mA, HART).

• Calibrate and test valve positioners.

• Calibration process indicators, recorders, controllers, PLC/DCS I/O cards.

• Measure and simulate thermocouple and thermistor signals.

• Provide power to the 2-wire transmitter and measure the loop current.

• Configure, diagnose, and maintain HART smart meters.

• On site instrument installation, debugging, and troubleshooting.

• Coordinate with Druck pressure module for pressure instrument calibration.
