Product questions
What pressure range does the ifm PI7993 measure?
The PI7993 measures relative pressure from -1 to 25 bar (-14.4 to 362.7 psi). Its 100 bar pressure rating is an overload limit, not the measurement range; avoid static and dynamic overpressure above that limit.
Does the PI7993 provide a 4–20 mA analog output?
No analog output is specified for this model. It has two configurable switching outputs; OUT1 can instead be configured as a diagnostic output. Check the control system’s input requirements before ordering.
What process and electrical connections does the PI7993 use?
The PI7993 has a G 3/4 process connection and an M12 electrical connector. Verify the fitting, seal, wiring and pressure range against the existing installation; provide the equipment model and serial number if replacement fitment needs confirmation.
Can the PI7993 be used with viscous or particle-containing liquids?
The listed applications include viscous media and liquids containing suspended particles. The sensor has a flush, no-dead-space design; confirm that the wetted materials, process connection and temperature limits suit the actual medium and installation.
