Product catalog summary
Measurement Methods:
Various pressure measurement methods are available, including RD Gauge pressure, RD/GP Gauge pressure with bell testing, RD/DF Gauge pressure with flow, DD Differential pressure, SD Stagnation Pressure, and MF Mass flow. The specific pressure ranges are detailed in the technical data.
ZEDcore Measuring Module:
The ZEDcore module is central to the ZED family and can be integrated into all ZELTWANGER measuring devices except ZEDeco. It features a modular design allowing for flexible and quick swapping of measuring circuits or modules across different devices. Optional accessories include an external venting valve and temperature compensation.
Application Examples:
The ZEDcore module is applicable in various industries, including automotive (engines, transmissions, hybrid drives), medical devices (catheters, dialysis filters), packaging/cosmetics (dosing pumps, plastic bottles), household appliances (water pumps, gas valves), and general industry (cylinders, valves, seals).
Technical Specifications:
The devices support multiple interfaces and expansion options, such as ZEDbox, ZEDbase+, ZEDmod, and ZEDflex, with varying channel capacities. The dimensions are 5.47 x 9.25 x 12.40 inches, weighing approximately 8-10 kg, and require a 24 VDC power supply. The test medium is compressed air, oil, and water-free per ISO 8573-1, Class 3.
Pressure and Measurement Details:
Test pressure ranges from vacuum to 232 psi, with accuracy at 1% FS. Measurement ranges align with test pressure ranges, with resolutions of 0.5 ppm from the end value. The smallest measurable pressure change varies by type, with measuring accuracy and repeatability dependent on the test setup.
Additional Information:
Further details on accuracies, test pressures, control options, and customer-specific protocols for data acquisition and evaluation systems are available upon request.

Gauge pressure (2 channels optional) RD / GP Gauge pressure with bell testing The heart of the ZED family – the ZEDcore measuring module – can be integrated into all ZELTWANGER measuring devices (except ZEDeco) and is easy to install with plug-and-play. Due to the modular design, measuring circuits in a device can be flexibly and quickly swapped out, or the measuring modules can be used in different devices. Application examples: · Automotive: engines, cylinder heads, transmissions, diaphragms, additional main devices, power adapters, hybrid drives, heat exchangers, control electronics, batteries, lines, valves, fuel cells, pumps, … · Medical devices: catheters, dialysis filters / boxes, irrigation / tube systems, septic fluid jars, syringes, external lungs, … · Packaging  / cosmetics: dosing pumps, plastic bottles, cartridges, … · Household appliances: water switches, water pumps, gas valves /  fittings, stoves, compressors, … · General industry: cylinders, safety / check valves, couplings, grippers, ball valves, seals, throttle pins, … RD / DF Gauge pressure with flow DD Differential pressure Stagnation Pressure Mass flow (Please refer to the technical data for possible pressure ranges) Accessories (optional):
