Data Logger econômico para temperatura, eventos e chuva UA-003-64

El Registrador de datos economico HOBO® UA-003-64 para Eventos registra eventos de contacto momentáneos y temperatura. 
Los datos de los eventos se etiquetan y almacenan en el momento en que suceden, lo cual resulta de una utilización eficiente de la memoria. Los datos de temperatura se registran a intervalos definidos por el usuario. El HOBO para Eventos es ideal para conectar a un Pluviómetro para registrar la lluvia.

Características

• Tipo de Evento externo: contacto por cierre de relé o 'volcados' de pluviómetro

• Rango de Medida de Temperatura: -20° a 70°C 

• Capacidad de Memoria: 64K

• El Número de puntos de datos depende del intervalo del evento:

    16K a 23K eventos sólo cuando se graban eventos

    25K a 30K puntos de datos cuando se graban eventos y temperatura.

El UA-003-64 es un registrador de datos de muy buena calidad con un coste economico

External event input

Event sensor: Two-wire interface suitable for measuring mechanical and electrical contact closures

Maximum input frequency: 1 Hz (1 pulse per second)

Lockout time: 500 ms

Minimum pulse width: 1 ms (hardware debounce)

Input/output impedance: 100 kΩ

Edge detection: Falling edge, contact closure, or Schmitt-trigger buffer

Preferred switch type: Normally open. For maximum battery life, the event input should be used with its preferred switch type. The logger will work with normally closed switches, but battery life will be compromised.

Open circuit input voltage: Battery voltage; nominally 3.0 V

Maximum input voltage: Battery voltage + 0.3 V

User connection: 24 AWG, 2 leads: white (+), black (-)

Temperature measurement

Measurement range: -20° to 70°C (-4° to 158°F)

Accuracy: ± 0.47°C at 25°C (± 0.85°F at 77°F), see Plot A. A solar radiation shield is required for accurate temperature measurements in sunlight.

Resolution: 0.10°C at 25°C (0.18°F at 77°F), see Plot A

Drift: Less than 0.1°C/year (0.2°F/year)

Response time: Airflow of 2 m/s (4.4 mph): 10 minutes, typical to 90%

Logger

Time accuracy: ± 1 minute per month at 25°C (77°F), see Plot B

Operating range: -20° to 70°C (-4° to 158°F)

Environmental rating: Tested to NEMA 6 and IP67; suitable for deployment outdoors

Drop specification: 1.5 m (5 ft) onto concrete

NIST traceable certification: Available for temperature only at additional charge; temperature range -20° to 70°C (-4° to 158°F)

Battery: CR-2032 3V lithium battery; 1 year typical use

Memory: 64K bytes

Materials: Polypropylene case; stainless steel screws; Buna-N o-ring; PVC cable insulation

Weight: 50 g (1.7 oz.)

Dimensions: 71 x 33 x 23 mm (2.8 x 1.3 x 0.9 inches); 1.8 m (6 ft) cable
