HIH-4000-003 HIH4000-003 Humidity Sensor Medical equipment
DESCRIPTION;
The HIH-4000 Series Humidity Sensors are designed specifically for
high volume OEM (Original Equipment Manufacturer) users.
Direct input to a controller or other device is made possible by
this sensor’s near linear voltage output. With a typical current
draw of only 200 µA, the HIH-4000 Series is often ideally suited
for low drain, battery operated systems.
Tight sensor interchangeability reduces or eliminates OEM
production calibration costs. Individual sensor calibration data is
available.
The HIH-4000 Series delivers instrumentation-quality RH (Relative
Humidity) sensing performance in a competitively priced, solderable
SIP (Single In-line Package).
Available in two lead spacing configurations, the RH sensor is a
laser trimmed, thermoset polymer capacitive sensing element with
on-chip integrated signal conditioning.
The sensing element's multilayer construction provides excellent
resistance to most application hazards such as wetting, dust, dirt,
oils and common environmental chemicals.
