Digital Pressure Sensor
Digital pressure sensor is also named silicon pressure sensor , which is different from metal capacitive pressure transmitter.
Digital pressure sensor is also named silicon pressure sensor , which is different from metal capacitive pressure transmitter, digigal pressure sensor has a LCD screen with backlight and power supply DC 24V/12V, can output current signal (4-20mA/0-20mA), voltage signal (0-5V/1-5V/0-10V). Pressure sensor has small dimension, light weight, high anti-vibration and anti-shock performance, long –term stability, measuring range -0.1~100MPa/ -1~1000bar/ -14~14503psi, medium temperature -40~+60℃ (-40~+140℉), for hydraulic/steam/air pressure/high-temperature liquid measurement.
KD99 Pressure sensor has optional output signal, such as 4-20mA/0-20mA/0-5V/1-5V/0-10V/RS485, Which is widely used in process control, aerospace, automotive, medical equipment, water treatment , Constant pressure control and environmental protection boiler ,HVAC and other fields
● The signal goes through special amplifier, then through volta current transforming, and transform corresponding signal of ran into standard 4~20mA/0~20mA/0~5VDC/1~5V/0~10VDC signal.
● Light weight and small size, convenient to install and operate.
● Works for gas, liquid which are not corrosive to stainless steel.
● Widely used to measure and control liquid and gas for aerospace, electric power, sewa treatment, water supply, petroleum chemical and pharmaceutical industryetc.
● Strong –anti-interface , good long –term stability
● Diversified pressure connection threads , easy for installation and use
● Standard models are in stock , fast delivery
● Digital LCD Display , easy to see .

1. The item must not measure acid fluid (below PH6); here is a simple judgment method: if you cannot touch the liquid with your hand, do not measure it with the item.
2. When installing the pressure transmitter, use a wrench to tighten the transmitter at the bottom nut (cable should be disconnected during installation), and do not rotate the upper part of transmitter directly.
3. Make sure the power supply output volta is conformed to the requirements of the probe, and ensure the maximum pressure of pressure source is within the measuring ran of the product.
4. Less than 0.03 Mpa vertical installation, in case it affects measurement accuracy.
5. When removing probe, make sure the equipment has been disconnected from pressure source, in case of causing casualties.
6. The sensor is a precision device, so user should not disassemble it by oneself, and do not touch diaphragm, in order to avoid dama to product.
7. Store the transmitter indoors in dry and ventilated environment of room temperature.
