1. Description

(1) Operating Principles

Adopting a single-chip microcomputer as the control core, the NSTH-A1T4 temperature & humidity transmitter obtains temperature & humidity data from the digital temperature & humidity sensing head and converts the data to standard

output signals of 4 mA to 20 mA. It features wide test scope, high precision, and stable & reliable performance.

(2) External Dimensions

External dimensions: 85 mm * 100 mm * 25.5 mm, as shown in the following figure:

Technical Parameter

3. Wiring

Red - positive polarity (+)

Black – negative temperature (-)

Yellow – negative humidity (-)

Note: The relationship between the power voltage of two-wire current-mode transmitter and the sample resistance is : 25 V > U > 9.5 V + Imax * Rsample (Imax = 20 mA).
