Threaded RTD Probes for Air with 4-20 mA Output
Probe
Replacement Transmitter
Replacement Element
A built-in transmitter converts the probe’s air-temperature readings to a 4-20 mA signal for use with switches, controllers, and data loggers. Consider the temperature of your application when selecting a probe. Choose a temperature range that closely matches your application to save time configuring the probe. For more flexibility, choose a probe with a large range. You can reconfigure probes for multiple applications.
Replacement elements include a ¼” probe, spring, and 3” of leads.
