Installation Guidelines

• Always gap the probe at the recommended 1.27 mm (50 mils) from an AISI 4140 steel target.
• Apply the specified torque to the probe case and connectors to ensure a secure fit.
• Maintain the minimum cable bend radius to prevent internal damage to the cable.
• Avoid exposing the probe to temperatures below -34°C to protect the internal pressure seal.
• For optimal linear range, maintain the supply voltage more negative than -23.5 VDC.
