Your Compact Vacuum Meters for 1600 to 5 x 10-4 mbar
Compact vacuum meters of the VD8 family are fully electronic and combine high quality sensors and modern microcontroller technology with a handy design.
Our customers appreciate these easy-to-operate gauges as reliable tools in plant engineering, service and laboratory.
The digital display of your vacuum meter shows the exact absolute pressure. Sensors with temperature compensation and sophisticated evaluation electronics guarantee precise and reproducible measurement results.
Optionally the vacuum meters can be used as datalogger in
order to store pressure data during the measurement. By push of a button those data are easily transmitted to a PC where they can be analysed and documented for your quality assurance using our VacuGraph Windows software.
Mobile use or fixed installation? Integrated or detachable sensor? Quick spot check of actual pressure or documentation of measurements on PC? The VD8 will always be in compliance with your wishes.
Further Advantages
- Display of minimum and maximum pressure
- Automatic switch-off or continuous operation
- High battery lifetime due to clocked measurement
- Operation with battery or mains adapter
- Robust stainless steel flange

Badotherm seals are available in stainless steel AISI316 as standard. They can also be manufactured in all known exotic materials. Naturally, our seals can be supplied with 3.1.B and other material identification certificates. The smallest diaphragm diameter offered is 23 mm / 1” and the biggest diaphragm is 89 mm / 3½”. At these dimensions the lowest possible measurement for a chemical seal mounted to a gauge pressure transmitter is 10 mbar and we can even reach as low as 2 mbar for a DP measurement. We offer a temperature range from –140 °C to a maximum temperature of 400 °C. With a wide choice of system fill fluids and diaphragm materials, the Badotherm chemical seal range is the most flexible and extensive available in the industry.
Badotherm seals can be added to virtually any pressure measuring device. Pressure gauges, transmitters, sensors and switches are all compatible. The purpose of a chemical seal is to protect instrumentation from extreme temperatures, and from aggressive, highly viscous, corrosive, heterogeneous abrasive, and toxic media’s. Chemical seals enable not only, hygienic connection of measuring instruments in the process industry, but can also be used for simple wastewater applications or more highly sophisticated process- and petrochemical applications

The J5 provides measurement of melt pressure and other process variables. The J5 features a large 5 digit display that can operate in either green or red or change color in case of alarm. The J5 is configurable from the front, or from a PC with a software tool. The main input is for Strain Gauge or linear DC voltage/current with square root extraction or with a 16 segment linearizer. The second input with DC voltage or current is suited to temperature indication and signal conditioning (min, max, average, ratio, etc.) when combined with the main input. The J5 has 3 digital inputs independently configurable for alarms, display and calibration handling. Up to four alarms with ISA-A acknowledge are available as well as a retransmission output and Modbus RS485 comms. The J5 has three levels of password protection and the front panel is IP65. The strain gauge bridge of the melt pressure or load cell transducer can be powered by an internally regulated 5 or 10Vdc. The reliability of the strain gauge is monitored continuously. A front panel calibration routine is provided to automatically remove zero and span offsets. The automatic calibration can also be activated by using front keys, one of the three digital inputs, or over serial comms. Tare function for load cells is provided.

The JOFRA range of IPI Industrial Pressure Indicators is ATEX and CSA certified for use in potentially explosive environments in the field or in calibration laboratories. ATEX is the primary intrinsically safe standard in the European Union, while CSA refers to relevant Canadian and USA standards.
Accurate to ± 0.05% FS, the IPI can be used as a calibration reference or in applications where high accuracy pressure measurement is required from safety valve checks to system pressure verification. This Ex certification will allow the IPI to be used in any industry where there is a risk of flammable gases. These include oil refineries, off-shore platforms, chemical plants, gas production plants, oil and gas shipping, pharmaceuticals and in whisky distilleries.

HVAC measurement device PascalMaxx for monitoring & control
Differential pressure instrument with membrane measurement technology for monitoring and control of differential pressures and air flows in HVAC applications. Suitable for rooms and ducts.
By the integrated switch the pressure conditions can be monitored and an alarm set in case of need. The also integrated analogue outputs (V and mA) can be used for a system control. The automatic Zero-Point calibration assures an accurate and reproducible measurement at any time and avoids any influence of the mounting position on the measurement results.

Diaphragm Seals with Thread or with Flange Connection, Models MDM 7210, 7211 and 7280
Chemical seals models MDM 7210 and 7211 consist of three separate parts: the upper housing with welded diaphragm, the lower housing and the attachment flange.
Different materials can be combined, and different connection types and sizes. This way, our chemical seals series MDM 72.. are available in suitable variations for innumerable applications and media.
The construction and function of these models are similar, but the allowed minimum and especially the maximum pressures differ.
MDM 7280 is constructed for higher pressure (400 or 600 bar). It has no separate attachement flange as the other models, but the upper and the lower housing are tied directly together by 6 bolts M 20.
