The TP temperature plug from ifm is
designed to replace cumbersome,
leaky boxes with modern electronics
and connector technology.

The company already supplies
type TT or TS Pt100 and Pt1000
temperature pickups with an integral
M12 connector for ease of
connection, a seal of at least IP67,
and a robust mechanical link. That
probe can now be plugged directly
into the TP, which will send the
resulting measurement as a 4-20mA
signal back to the panel via another
M12 sealed connector.

Using M12 connectors all round
means the transmitter can be
mounted anywhere between the
probe and the panel.

The company says the TP is a
fraction of the size of a head
transmitter, robust, and can be scaled
from a PC using a USB interface.
