IFM SI5002 - Flow Monitor, M18 Process Connection, IO-Link

Q: What flow velocity range does the IFM SI5002 measure?

The SI5002 measures flow velocity from 3 to 300 cm/s in liquids and from 200 to 3000 cm/s in gases.

Q: What measuring principle does the SI5002 flow monitor use and what media does it suit?

It is a thermal (calorimetric) flow monitor with a 45 mm probe length, suitable for liquids and gases.

Q: How accurate and responsive is the IFM SI5002?

Switch point accuracy is +/- 2 to +/- 10 cm/s (water, 25 C, factory setting) with a repeatability of 1 to 5 cm/s and a response time of 1 to 10 seconds.

Q: What outputs does the SI5002 provide?

It has 2 digital outputs of PNP design, configurable as switching signal or IO-Link, rated at 250 mA permanent current with a maximum voltage drop of 2.5 V DC, and short-circuit and overload protected.

Q: Does the SI5002 support IO-Link and at what specification?

Yes, it supports IO-Link revision 1.1 with COM2 transmission at 38.4 kBaud.

Q: What is the operating voltage and current consumption of the SI5002?

The SI5002 operates on 18 to 36 V DC and draws less than 60 mA.

Q: What is the housing material and IP rating of the IFM SI5002?

The cylindrical housing is made of stainless steel (316L/1.4404 and 301/1.4310), PC, PBT-GF20 and EPDM/X, with protection rating IP 65 and IP 67.

Q: What are the process and electrical connections of the SI5002?

The process connection is an M18 x 1.5 internal thread and the electrical connection is 1 x M12 A-coded 4-pin connector; operating temperature is -25 to 80 C.

SI5002 Applications

The IFM SI5002 is a calorimetric flow monitor used for reliable monitoring of liquids and gases in pipes. It is suited for pump-protection, cooling-water and lubrication flow monitoring, and dry-run detection in industrial machinery. Variable process connection via adapters allows flexible installation, switch points are set quickly by pushbutton or IO-Link, and the 10-segment three-colour LED bar graph clearly indicates flow and switch point. The robust stainless steel housing withstands harsh industrial and washdown environments.
