Oxygen Sensors

Today, Fujikura is the pioneer of the zirconium-based, current limiting oxygen sensors. This style of sensor has many advantages over other ways of measuring oxygen.

The sensor module FCX-MCXX is a complete solution for measuring oxygen within the range of 0.1 - 25% or 0.2 - 95%. The sensor and electronics are integrated on one board. The MC module delivers a linearized analog output signal of 0-20 mA, 4-20 mA, or 0-10 VDC. Digital outputs of RS-232, RS-485 or I²C are available upon request.

The sensor module FCX-MLXX is a complete solution for measuring oxygen within the range of 0.1 - 25%. The sensor and electronics are integrated on one board. The module takes the signal directly from the sensor and amplifies it into a nonlinear but logarithmic 4-20 mA output.

HYT R411 Low Temperature Humidity Sensor

HYT R411 is a fast-responding digital humidity and temperature sensor which has a very wide temperature range from -90°C to +50°C.

HYT 939 Hermetically Sealed Digital Humidity Sensor

Based on the HYT939 humidity sensor, the HYT939 MOD, is a digital humidity and temperature probe designed for sophisticated industrial applications. Resistant to pressure up to 16 bar, the probe location is about 28 mm in length with a cable length specified at order placement.

HYT 221 Splash-Proof Digital Humidity Element

HYT 221 is a digital humidity element in a round stainless steel casing which can be easily fitted into housing openings and can be sealed against the wall with the use of an O-ring. In combination with the waterproof membrane filter, it results in an assembly that is splash waterproof and enables a sealed housing construction while providing high dynamic responsiveness.

HYT 939 has a welded, hermetically sealed TO 39 housing with glass grommet and sinter filter designed for compressed air systems up to 16 bar. Due to the humidity calibration process and special polynomial correction method, a high accuracy of ±0.1% rH is achieved in the the low humidity region of 0-10% rH up to 50 ppm water content. The sensor is suitable for dew point measurements up to -40C dp, such as for the evaluation of medical compressed air quality.

HYT 271 Digital Humidity Element With I2C Interface

The HYT 271 combines the advantages of a precise, capacitive humidity sensor with the high functionality of an ASIC. Integrated signal processing provides relative humidity and temperature over the I²C compatible interface as digital values. The module is factory calibrated and any further alignment by the user is not necessary. Both linearity and temperature drift are corrected by on chip calibration, providing excellent accuracy over a wide range of temperature and humidity.
