1. INTRODUCTION
The Temperature Transmitter TEMP-WM and TEMP-DM are microprocessed-
based instruments that incorporate high-accurate and stable sensors whose
information is converted to linear 4-20 mA or 0-10 Vdc. As they are microprocessed
equipment, they can be totally configured through the communication interface
ATxConfig and ATxConfig software.
The TEMP-WM model is intended for wall mounting. The TEMP-DM comes with
a probe tip for duct or wall mounting.
2. PRESENTATION
Technical Parameters
Accuracy: 0,5 ºC @ 25 ºC (1.6 °C for the entire measurement range);
Range: Configurable between -50 and 120 °C;
Default: 0 to 100 ºC
Operating limits:
TEMP-WM: Electronic circuit: -20 to +65 °C
TEMP-DM: Electronic circuit: -20 to +65 °C
Sensor and probe: -40 to +100 °C
Note: For temperatures above 65 ºC or below -20 ºC, a maximum of 50% of the probe length (TEMP-
DM) should be exposed to this temperature, to avoid conducting extreme temperatures to the electronic
module.
Response time:
Up to 30 seconds in slow moving air.
Power supply:
4-20 mA model: 12 Vdc to 30 Vdc
0-10 V model: 18 to 30 Vdc / 15 mA max.
Outputs: 4-20 mA or 20-4 mA current, 2-wire loop power supply
0-10 Vdc voltage / 2 mA max.
Output Load (RL):
4-20 mA model: RL (Ohms max) = (Vdc – 12) / 0.02
let Vdc = Loop power supply (12 to 30 Vdc)
