• Adjustable pressure relief valve for setting maximum output pressure
• Integral fine control and pressure release valve
• Lightweight, handheld, easy to use

GE's PV210 low-pressure pneumatic hand pump is fully portable, easy to use, and generates pneumatic pressures in excess of 3000 mbar (43 psi). It is an ideal tool for calibration checks on pressure transmitters, pressure switches, indicators, recorders, and controllers.

PV210 be used as a portable pressure comparator in conjunction with various pressure indicating devices. This precision pneumatic hand pump includes a unique user-adjustable pressure relief setting, enabling the setting of maximum pressure.

• Dual-source of pneumatic pressure and vacuum
• Finger-tight quick fit connectors
• Extremely low pressures generated by using the fine adjust vernier alone
• Built-in pressure relief valve for setting maximum output pressure
• Fine control needle valve for pressure release

The DPI 104 is a microprocessor-controlled digital pressure gauge that combines precision and functionality in a compact, robust and simple-to-use package. The DPI 104 matches advanced silicon sensor technology with several convenient design features, resulting in an accurate, versatile yet affordable digital test gauge. Supplied as a stand-alone process indicator or in a kit with the widely proven Druck hand pumps, the DPI 104 provides a reliable and economic solution for a wide range of pressure sensing applications.

Applications

• Process monitoring and control
• Test and calibration

• Accuracy
• 0.05% FS including non-linearity, hysteresis, repeatability and temperature effects from 14°F to 122°F (-10°C to 50°C)
• Resolution
• Maximum five digits
• Burst Pressure
• Burst pressure is 2x working pressure (exception, 20,000 psi (1400 bar); burst pressure 29,000 psi (2000 bar).
• Selectable Pressure Units
• kPa, MPa, kg/cm2, psi, mbar, bar, inHg, inH2O, mH2O, mmH2O and mmHg
• Display
• Pressure reading: 5 digits with 0.5 in (12.7 mm) character height
• Full scale indicator: 2.5 digits with 0.25 in (6.35 mm) character height
• Pressure Bar Graph
• In addition to the numeric pressure indication, the DPI 104 LCD display contains a circular twenty segment bar graph to provide the user with a quick visual estimation of pressure from 0 to 100% full scale output. The bar graph increments represent 5% of the user- selectable range.
• Display Update
• Two times per second
• Minimum/Maximum Values
• The minimum and maximum pressure values can be displayed on the DPI 104. This function can be enabled/disabled, and reset by the user.
• Switch Test
• The DPI 104 features a switch test function that will capture and display the open and closed values from an external pressure switch. Maximum switch impedance 200 Ω.
• Voltage Output
• The DPI 104 can be programmed to provide a 0 to 5 V output signal that can be configured as directly proportional to the pressure shown in the display or set to a fixed value. The voltage output mode provides 0.1% FS accuracy from 50 mV to 5 V.
• Alarm Output
• The alarm output consists of an open drain field effect transistor (maximum current 250 mA, maximum voltage 24 VDC).
• Adjustable Mounting Positions
• For added convenience, the DPI 104 housing will rotate 320° around the pressure fitting and the faceplate can be rotated in any orientation for optimum visibility.
• Menu Lock
• To guard against unauthorized menu access, the DPI 104 features a menu and tare lock function.
• RS232 Interface
• Serial communications are provided to allow transfer of data to a PC with the optional serial lead (IA4090-2-V0). Using this link, all menu commands and display data are available via an ASCII command set or the optional SiCal Pro Software.
• Network Capability
• Up to 99 DPI 104 instruments can be connected together in a daisy chain-configured network.
• Universal Pressure Module (UPM) Capability
• UPM modules can be connected to the DPI 104 to enhance the accuracy and extend the pressure range.
