Positron Series ASH — 22mm Body · ±5 to ±100 mm · IP65 · High Temperature

Key Specifications
Positron Series ASH
The Series ASH is the high-temperature variant of the Positron AC LVDT family. In an all-stainless-steel construction with IP65 protection, it is designed for continuous operation in elevated ambient temperature environments where standard sensors cannot survive.
Available in two temperature variants — ASH-120 (up to 120°C) and ASH-150 (up to 150°C) — the Series ASH covers ±5mm to ±100mm across 6 standard models. A PTFE-insulated shielded cable is fitted as standard. Requires a standard external signal conditioner (±15V AC, 2V rms @ 2kHz).
Models
| Model | Full Stroke Range | Body Length (mm) | Sensitivity (mV/V/mm) | Accuracy (% FSR) |
|---|---|---|---|---|
| 005ASH | ±5 mm (0–10 mm) | 93 | 14 | ±0.25% |
| 010ASH | ±10 mm (0–20 mm) | 123 | 8 | ±0.25% |
| 025ASH | ±25 mm (0–50 mm) | 185 | 3 | ±0.25% |
| 050ASH | ±50 mm (0–100 mm) | 337 | 2 | ±0.3% |
| 075ASH | ±75 mm (0–150 mm) | 443 | 1 | ±0.3% |
| 100ASH | ±100 mm (0–200 mm) | 476 | 0.8 | ±0.4% |
Mechanical stroke exceeds FSR — see datasheet for details. ASH-120 and ASH-150 temperature variants available for all models.
Use Cases
Continuously measure displacement of doors, hearth elements, or structural members inside high-temperature industrial furnaces and kilns.
Track ram or platen position in vulcanising presses, laminating machines, and hot-moulding equipment where ambient temperatures routinely exceed 100°C.
Measure specimen deflection in elevated-temperature fatigue testers and creep test machines with accurate, frictionless feedback.
Monitor blade deflection, case distortion, and thermal expansion in aero engine test cells and turbomachinery development rigs.
All-stainless-steel IP65 construction suits subsea and offshore deployment environments where standard sensors would fail.
Provide reliable position feedback in hot-rolling mills, glass-forming machinery, and high-temperature process automation systems.
