Humidity and temperature sensor

El termohigrómetro UTA de NESA es un sensor combinado de temperatura y humedad relativa del aire, conforme a los estándares técnicos de la Organización Meteorológica Mundial (OMM). Existe una versión con ventilación forzada (código UTAV); la ventilación natural corresponde al código AHU.

Temperatura: elemento sensor RTD Pt100 clase 1/3 DIN (100Ω @ 0°C). Rango de medición típico: -40 ÷ +60 °C (-60+70 °C disponible). Resolución: 0,01 °C. Precisión: DIN 43760 1/3DIN (±0.1°C @ 0°C). Tiempo de respuesta: < 8 s. Salida directa Pt100 con conexión de cuatro hilos, o señal normalizada en corriente (4–20 mA), voltaje (0–2 Vdc) o comunicación digital RS485 con protocolo Modbus.

Humedad relativa: tecnología capacitiva de baja potencia (<0,1 W), con película delgada. Rango de medición: 0 ÷ 100 % de humedad relativa. Resolución: 0,05 %. Precisión: ± 2% f.s. Tiempo de respuesta: < 8 segundos (10÷80 % de humedad relativa). Salida en voltaje (0–1 Vdc), corriente (4–20 mA) o digital RS485/Modbus.

Señal de salida según código:

  • N: 0÷1 Vdc (Rh) y pt100 (T).
  • A: 0÷1 Vdc (Rh) y 0÷2 Vdc (T).
  • B: 4÷20 mA (Rh) y 4÷20 mA (T).
  • C: 2 x RS485/ModBus.

Condiciones de funcionamiento: -50 ÷ +80 °C (-60 ÷ +80 °C disponibles). Alimentación: 10÷28Vdc (típ. <0.1W, máx. 2W@12Vdc mod. TAV). Protecciones: contra inversión de polaridad y descargas atmosféricas. Material: aleación de aluminio anodizado y tornillos de acero inoxidable. Peso: 680 g.

Aplicaciones: estaciones meteorológicas automáticas, sistemas de climatización (HVAC), control ambiental en invernaderos, laboratorios, almacenes. Integración en sistemas SCADA, PLC o redes de monitoreo remoto.
