Features

Druck Precision Portable Pressure Calibrators

The DPI 605 precision pressure calibrator provides a simple and cost effective means of meeting the calibration requirements of ISO 9000 and other similar quality standards. The instrument, which combines micromachined silicon piezoresistive and resonating element sensors with the latest microprocessor technology, features 0.025% of reading accuracy. It is a totally self contained, battery powered pressure test and calibration system. Standard features include electrical measurement and supply capability, pressure and vacuum generation, simultaneous displays of pressure/vacuum and electrical parameters, extensive data processing and storage capability and RS232 interface.

To simplify field calibration and the collection and transfer of data, if offers a wide range of standard functions. Peak readings, switch testing, data logging, leak testing, limit setting and results analysis all add to the versatility of this instrument. Test data is safely stored in the non-volatile memory and, when the calibration work is completed, can be easily downloaded into the computer. Druck also offers auto calibration and data analysis software specifically designed to run on a PC. This enables completely automated calibrations to be carried out with the DPI 605.

Total Quality Management

The DPI 605 is a powerful tool in the support to quality management systems. Together with data analysis and auto calibration software, it can perform an almost limitless range of pressure calibration and test functions. Reports for up to 40 independent 20-point calibrations can be stored. Routine Calibrations can be transferred

from the data base to the DPI 605 and results downloaded to update records, analysis and histograms, etc. The complete system permits audit trail compliance with all of the major quality management standards, FDA validation and OSHA requirements.

The simple keypad operation of the DPI 605 provides easy and rapid access to all the calibration and test facilities.

Pressure Key Functions

These keys define the desired pressure measurement parameters.

Range

This is used to select an internal or external transducer and the gauge, absolute or barometric pressure reading.

Units

Up to four alternative pressure units are immediately available.In conjunction with the SET-UP key, 24 pressure units can be assigned to the instrument.

Limits

This key is used when it is necessary to protect the instrument under test from pressure overload. A safety limit will block the pump action at the desired maximum pressure and trigger an audible alarm.

Process

The process key allows access to a range of functions:

• Tare_provides a facility to offset the displayed pressure reading by either the currently displayed pressure or a manually entered value.

• Peak_records the maximum and minimum pressure levels obtained during operation.

• % full scale (FS)_converts the indicated pressure reading to a % FS reading over the operator defined zero and FS range.

• Filter_this will stabilize the display if the instrument is connected to a fluctuating pressure line.

Zero

Used to remove display zero offset

Pressure/Vacuum

Changes the operation of the hand pump from pressure generation to vacuum generation

Pressure and vacuum generation and adjustments are achieved by an integral hand pump and volume adjuster, with a release valve for venting. When it is important that the maximum pressure for the unit under test is not exceeded, a safety LIMITS function may be selected to automatically block the pumping action at the desired set pressure.

The advanced sensor and thermal compensation technologies employed allow the standard instrument to cover a range of -14.7 to 300 psi (-1 to 20 bar). Unlike competitive calibrators, it is not necessary to purchase multiple pressure modules to test units over this range.

An indicator version is available for operation up to 5000 psi (350 bar) with internal transducers, and up to 10,000 psi (700 bar) with external transducers. The indicator includes all the features of the calibrator except for the integral pressure and vacuum generation capability.

For barometric pressure measurement, a high accuracy resonating silicon pressure transducer is added to the instrument. This sensor allows simulation of other absolute pressures by adding the barometric value to the gauge measurement. In addition, an optional temperature probe can be supplied for temperature measurements up to 400°F (200°C).

The DPI 605 features an impact resistant, splash and dust proof enclosure. All of the main controls are via a membrane keypad and the LCD graphics display is mounted behind a tough polycarbonate window. The display can be illuminated when measurements have to be made under poor lighting conditions. All of the electrical input and output connections are recessed into the sides of the enclosure to avoid accidental damage. The instrument weighs only 9 lb (4 kg) and is supplied with a carrying case that contains a separate storage compartment for test leads and other accessories.

Electrical Input Key Functions

Four keys control the digital multimeter facilities of the instrument.

Volts

Measures ±50 V with 0.01mV maximum resolution

Measures ±55 mA with 0.001 mA resolution

Temp

With the optional PT 100 platinum resistance probe, the instrument provides a temperature measurement display. The scale is from -60°F to 400°F (-55°C to 200°C) and the units are selectable as °F or °C.

Electrical Output Key Functions

These two keys are used to configure the electrical outputs as either a fixed voltage or current , programmable via the keypad, or an analog output of any of the measured parameters, i.e. pressure, temperature, voltage and current.

Volts

Programmable within the range 0 to 24 V

Programmable within the range 0 to 55 mA

Mode Select Keys (blue keys)

The nine mode select keys provide access to a variety of functions

On/Off

Switches the instrument on or off. The DPI 605 can be programmed to automatically switch itself off after a defined period of inactivity.

Display Light

Improves viewing visibility in poorly lit locations. Can be programmed to switch itself off after a defined period of time.

Set-up

Enables selection of the following variables:

• Units_24 pressure scales

• Temperature_°F or °C

• Comms_to set up the RS232 communication parameters, i.e. Baud-rate, Parity, Handshake.

• Auto off_provides automatic power saving.

• Clock_permits operator to set up time and date functions.

• Calibration_provides access to calibration parameters. A password (PIN #) is required before entry is permitted.

Switch Test

This key configures the instrument to test pressure switches. The pressure display indicates the applied pressure and status of the switch contacts. When the pressure is varied and the switch contacts change, the display records the event, i.e. switch contacts opened at 50 psi (3.5 bar) and closed at 30 psi (2 bar).

Data Log

This enables the DPI 605 to act as data logger and store up to 10,000 readings. Record and Replay facilities are included:

• Record_provides for entry of tag number, selection of data log trigger (internal or external), selection of stop event (time or number of samples), and set up of start delay time.

• Replay_is used to either recall any selected data log file to the display, or to download the stored data to an external printer via the RS232 port. The data can be presented in a numerical or graphical format. The graph can be displayed as pressure vs time, electrical vs time or pressure vs electrical.

Leak Test

This function provides a leak test facility for the unit or system under test. The display is reconfigured to indicate pressure drop and leak rate. Three additional functions are allocated to this facility:

• Wait_delay the start to allow pressure setting

• Time_the duration of leak test period.

• Reset_resets leak test display values to zero on completion of the test.

Display

The DPI 605 incorporates a clear, high resolution LCD which provides excellent viewing visibility under a wide range of plant conditions. Display presentations are available for virtually every pressure calibration and test requirement. To simplify the calibration process, electrical parameters are positioned alongside the pressure data.

Interface

The DPI 605 is both a versatile calibrator and flexible instrumentation system capable of interfacing with numerous options, inputs and outputs. Connections are located in protected areas at the two sides of the case.

Located in the left-hand side of the instrument are the

0.15 in (4 mm) electrical connections. These sockets can be considered as two functional groups. Depending on the selected mode, the first Group A,B,C&D provide;

Auto Cal

Permits the storage of up to 40 independent 20 point calibrations together with the tag numbers of the units under test.

Store

Snapshot memeory allows the current display to be stored in one of 20 memory locations.

Recall

programmable voltage/current outputs (B-C), transmitter simulator output (C-D), switch test input (A-B) and trigger signal input (A-D).

The second group I, COM and V, provide the input to the built-in digital multimeter (DMM). Current inputs are applied between the common (COM) and I terminals. Voltage inputs are applied between the (COM) and (V) terminals.

Positioned on the right hand side of the instrument are the multiway connections. These connectors are splash proof with spring closed covers for protection. Each connector has a different pattern and will only mate with a corresponding plug. The sockets are allocated as follows:

Power adaptor/battery charger (power) Temperature probe (temperature probe) RS232 serial data interface (RS232) External transducer (external transducer)

Pneumatic Circuit

The Calibrator version of the DPI 605 has a built-in hand pump to generate either pressure up to 300 psig (20 barg) or vacuum to -22 inHg (-850 mbar) gauge. Latching solenoid valves provide pressure limiting features, pressure/vacuum change-over of the hand-pump and low range transducer protection.
