ChipCap2 a Fully
Calibrated Humidity and Temperature
Sensor
ChipCap 2 offers the
most advanced and cost effective
humidity and temperature sensing
solution for virtually any type of
application. A capacitive polymer sensor
chip and a CMOS integrated circuit with
EEPROM are integrated into one embedded
system in a reflow solderable SMD
package.
Individually
calibrated and tested, ChipCap 2
performs at ±2% from 20% to 80% RH (±3%
over entire humidity range), and is
simple and ready to use without further
calibration or temperature compensation.
ChipCap 2 provides
linear output signals in various
interfaces to customer requirements:
- I²C interface
- PDM convertible

EMD
首先，EMD-2000传感器因严格的准确度和很强的耐化学性而出名。EMD-2000，不但提供高精度，而且改善滞后现象和轻巧型的尺寸。两个传感器都是块状聚合物相对湿度传感器，其电阻随着相对湿度的变化而变化。现在，EMD-4000能够承受存在有机物蒸气的环境。从冷凝环境恢复过来，可在温度达185°F
(85°C)的情况下使用
EMD
相对湿度传感器特别适合湿度测量应用，对精度要求很高，无需校准。EMD-2000传感器含有一个过滤盖，用于搬运时保护传感器，使污染物不影响其性能。
EMD-4000能够现场测量有机液体（如变压器油、汽油、甲苯、丙酮以及其他改变氢键强度的化合物）的水溶性。EMD-4000具有良好的可重复性和可交换性。

注意 |
--直流电源对EMD-4000湿度传感器不适用。直流电源的应用会使传感器极化，导致不可逆的转变。
只能采用对称的交流励磁电流。GE推荐采用低电平交流励磁（通常为1

KHz)，以使自热效应达到最小化。 |

ChipCap温度与湿度传感器
ChipCap系列湿度传感器在准确测量相对湿度领域提供了一个新的标准。基于电容式高分子传感技术，此设备为单个系统芯片(SoC)解决方案提供信号调理和温度补偿。此设备使用简单，其精度在交付前经全面测试与校准—无需再校准。
ChipCap可归为组件或传感器成品，符合客户规格要求。20%到80%RH时，测量精度为±
2%，在整个湿度范围内，测量精度为± 3%。具有良好的长期稳定性。0°C 到
+70°C时，温控精度为 ± 1°C。双组输出与0V 到 1V或0.5V 到
4.5V比率计一样提供湿度和温度或采用数字输出(ZACwire单线接口)。
