Principais características

Room temperature measurement
Complete with sensor and transmitter
4...20 mA output in 2-wire connection
Easy mounting
Measurement range 0...70°C
Supply 8...35 VDC

VISÃO GERAL

Electronic temperature measurement in for instance control rooms, offices, heating plants, factories, living rooms, and similar dry rooms.
Suitable as a transmitter for controllers, trip amplifiers, displays, or superior SCADA systems.

DETALHES TÉCNICOS

A precision Pt100 sensor with a small mass is mounted on the transmitter input thereby achieving a fast response time.

The 2-wire output signal of 4...20 mA is proportional and linear to the temperature value that influences the built-in sensor.

A reversed output signal of 20...4 mA may be ordered.

A number of different sensor error detection options may be ordered.

Protected against polarity reversal.

The bottom of the cabinet can be attached to a wall by two screws.

Visible or hidden cable access.
