Ceramic Pressure Sensor Capsule | 18mm Diameter | PTi18

Ceramic Pressure Sensor Capsule | 18mm Diameter | PTi18

Miniature and Hermetically Sealed with Superb Long-Term Stability
Category: Tags: , ,

Description

The PTi18 ceramic pressure sensor capsule is intended for use by OEM manufacturers of machines and equipment where the integration of pressure sensing or monitoring is required.

The compact 18mm diameter body design is suited to a wide range of applications including battery-powered, handheld devices where the PTi18’s high 11kΩ ensures minimal current draw and maximum battery life.

To ensure that the PTi18 ceramic pressure sensor capsule meets its specification when installed, it is essential to ensure that it is mounted correctly.  We will provide all the information required including engineering drawings to ensure successful incorporation into your product.

Features

  • Ranges: 0-1bar up to 0-600bar Gauge or Absolute
  • Output: 2.8-5.0mV/V (dependent on range)
  • Bridge Resistance: 11kΩ ±20%
  • Accuracy: <±0.25%/FS typical
  • High Purity Al2O3Alumina Ceramic
  • Very Compact 18mm Body – Ideal for OEM Applications
  • Excellent Long-Term Stability thanks to the Direct Fusion of Wheatstone Bridge onto Sensing Element
  • Hermetically Sealed for Direct Installation into OEM Equipment.
  • Low Operating Current = Maximum Battery Life
