- Pressure connections - 1/8 NPT or BSP male thread for calibrator, 1/8 NPT or BSP female for the user connection.
- Maximum pressure - The system should not be pressurized above 500 psig (35 bar).
- Orientation - The IDT 600 is designed for use in the vertical position and should be removed from the calibrator during transit.
- Pressure media - Gases compatible with stainless steel, acrylic and nitrile o-ring seals.
- Simple to use - The IDT 600 is fitted to the calibrator and the device under test is connected to the upper 1/8 NPT or BSP female port. Any dirt or moisture is then trapped inside the transparent chamber giving the operator an opportunity to clean the trap before contamination occurs.

The filling glass is used for filling measuring systems with
liquid testing media prior to adjustment or calibration.
The liquid test medium in the filling glass is sucked into the
measuring system by evacuation of the measuring system
and subsequent venting. On the vacuum side it is fitted with
a threaded connection G ½ male and on the measuring
instrument side with a knurled nut M28 x 1.5 with changeable
threaded insert G ½.

Accessories for Pressure Calibration – Adapters, Media & Tools for Precise Results
Pressure calibration accessories include everything required for repeatable, traceable pressure tests: adapters & fittings (G/NPT/UNF, flat-sealing/tapered), hose assemblies and high-pressure fittings, valve blocks/manifolds, seal kits (NBR/FKM/PTFE), media (calibration oil/water), fine volume controllers, check and vent valves, pressure relief, transport/mounting aids, plus software & documentation templates.
ICS Schneider Messtechnik configures compatible accessories for pneumatic and hydraulic setups—matched to pressure range, medium, thread standard, and the desired measurement uncertainty.
FAQ on Accessories for Pressure Calibration
Answers on selection, leak tightness, thread standards, media, safety, care, and best practices in everyday calibration work.
Which adapters do I need for G/NPT/UNF?
| Standard | Typical sizes | Sealing | Note |
|---|---|---|---|
| G (ISO 228) | G 1/8, G 1/4, G 1/2 | Flat-sealing | Widely used in EU |
| NPT (ASME) | 1/8", 1/4", 1/2" | Tapered (sealant required) | Common US standard |
| UNF | 7/16-20 etc. | Taper/flat depending on design | Often on reference devices |
Flat-sealing or tapered—what’s better?
Flat-sealing makes repeatable tightness easier with frequent changes. Tapered connections (e.g., NPT) are robust but require suitable sealant and correct tightening torque.
Which hoses/fittings for high pressure?
Above 350 bar use pressure-rated high-pressure hoses with sufficient burst margin. Combine fittings per manufacturer approval and check regularly for micro-leaks and aging.
What is a valve block/manifold for?
It enables isolation, venting, bleed, and precise approach of setpoints; ideal for switch tests (set/reset point) and leak tests.
Which medium should I use?
| Medium | Application | Advantage | Note |
|---|---|---|---|
| Dry air/N₂ | Pneumatics | Clean, no contamination | Drying/filtration required |
| Calibration oil | Hydraulics | Stable pressure generation | Check material compatibility |
| Water/glycol | Hydraulics | Clean, eco-friendly | Corrosion protection & proper venting |
How do I avoid leaks with frequent changes?
- Use flat-sealing quick adapters
- Keep sealing faces clean; stock PTFE/fiber gaskets
- Apply torque to spec; avoid side loads via hoses
What is a fine volume controller good for?
It enables very small pressure changes for stable readings, reduces overshoot, and improves repeatability at calibration points.
Which seals are suitable?
NBR (standard), FKM (higher temp/chemicals), PTFE (chemically resistant, flat-sealing). Choose according to medium/pressure.
Do I need check or vent valves?
Yes. In hydraulics, bleed/vent is essential; check valves protect references from backflow. In pneumatics, vents prevent drift from trapped air.
How do I run a safe leak test?
Pressurize to setpoint, isolate, allow to stabilize, then record pressure decay vs. time; document temperature to assess volume effects.
How should hoses/adapters be maintained?
- Regular visual checks (cracks, kinks, threads)
- Protect sealing faces; use dust caps
- Remove media residues; use compatible cleaners
Is there dedicated gear for pressure switch tests?
Yes: manifolds with fine restrictor, electrical taps (relay/PNP/NPN), and a signal logger to capture set/reset points and hysteresis.
How do I integrate accessories into a calibration case?
Use foam inserts, quick couplings, and labeled kits (size/standard). Frequently used parts remain protected and quickly accessible.
Do I need pressure relief?
Recommended. Overpressure protection safeguards references/DUTs and allows fast, safe depressurization after measurement.
Which software/documentation helps?
Templates for calibration reports (CSV/PDF), uncertainty budgets, and asset master data. Many references support USB/RS-485 for direct export.
Tips for repeatable results
- Keep line length & dead volume short
- Use consistent ramp-up/down procedures
- Hit each point multiple times, average & document
Does ICS Schneider support selection?
Yes. We review medium, pressure range, standards and recommend compatible adapters, hoses, and valve blocks, including accessory bundles—on request with DAkkS/ISO calibration.
