Frequently Asked Questions (FAQ)

• Q: Can I use this transducer with a 3/4-14 NPT mounting? Yes, option 02 provides 3/4-14 NPT threads required for the standoff adapter.
• Q: What happens if I supply voltage above -23.5 Vdc? A more positive voltage than -23.5 Vdc reduces the linear range.
• Q: Does the housing withstand impact at low temperature? BASEEFA certified two separate 4 Joule impacts at -39 °C (-38 °F).
• Q: What is the maximum probe cable length? Standard probe cable is 1 meter; field wiring can extend up to 305 meters.
