Sales probe type temperature and humidity transmitter production

EE220 is a temperature and humidity transmitter with a digital measuring probe, designed specifically for clean spaces and
Designed for special industrial plants. The calibration data of the plug-in probe is saved in the microprocessor inside the probe
In the chip, exchanging digital probes between any two transmitters does not affect the measurement results.
Performance HC105 humidity sensitive element, precise calibration method, and new microprocessor
The technology ensures that the instrument can achieve good long-term stability and precision within the full range
Accurate measurement results.
To meet special installation measurement requirements, the EE220 transmitter allows the measurement probe and transmitter to be connected
Place the device body in different installation areas, and then connect them through connecting cables
Connect them together to form a split structure, with cable lengths of 2 meters, 5 meters, and 10 meters
The probe can withstand a high working temperature of 80 ℃. The output signal measured by the transmitter can be
The voltage signal of 0-1/5/10V DC can also be a current signal of 4-20mA DC,
Multiple temperature ranges are available for users to freely choose from.
EE220 series transmitters are usually installed on the wall. Instruments can be optionally equipped
The digital display module of the LCD screen is used for direct on-site reading. Meanwhile, choose
The flange component can also be easily installed on the air duct to meet the on-site needs of measuring probes
Different installation requirements.

Online calibration of relative humidity and temperature:

In the pharmaceutical and biochemical industries, the FDA recommends using loop calibration methods for temperature and humidity measurement
Method, which refers to calibrating the complete measurement circuit composed of transmitters, connecting cables, and recording control devices
accurate To meet the technical requirements in this field, only a humidity generator and temperature generator are needed on-site
The device can calibrate the humidity probe and temperature probe of EE220 separately. Through the instrument PCB board
By pressing the button, it is easy to adjust and verify the temperature and humidity output signals.

Reference probe:

For the convenience of on-site debugging work, a fixed temperature and humidity output system has been specially designed for EE220
Reference probe, as a debugging tool for engineers. It can be used to detect the function and precision of the transmitter
It is also used for channel testing of control circuits. After replacing the reference probe, the transmitter can be effectively checked
The output signal of the analog channel and the display data of the measurement circuit can be easily checked for upper and lower limit alarms
Function. It is recommended to choose two reference probes during debugging, one to simulate high humidity and low temperature output, and the other to simulate
Output low humidity and high temperature.
