Product Description SPB83 series intelligent pressure transmitter adopts 16-bit microcontroller, its powerful functions and high-speed computing ability to ensure the basic performance of the transmitter, the whole design framework focuses on reliability, stability, high accuracy and intelligence to meet the increasing requirements of industrial field applications. Digital signal processing technology is adopted in the software, which makes it have excellent anti-interference ability and zero stability, and it has the ability of automatic zero stability tracking (ZSC) and automatic temperature compensation (TSC), and the powerful interface function can ensure good man-machine interaction without the need of hand manipulator. The digital meter head can display various pressures, liquid level heights and percentages, and the key operation can also conveniently complete the zero migration, range setting, damping setting and other basic parameter settings without a standard pressure source, which greatly facilitates on-site debugging and the use of the user.Technical Parameter Accuracy0.2%F·S, 0.5%F·SMeasuring range-0.1…0bar to -1…0bar 0…0.1bar to 0…600bar to -1…25bar relative 0…1bar to 0…35bar absoluteLinearitySuperior to 0.25%F·SStabilitysuperior to 0.25%F·STemperature driftsuperior to ±0.75%F·S (0…50oC)Response time≤10mSPower supply24VDC or (12VDC…36VDC optional)Output4…20mADCLinearitysuperior to 0.2%F·SAmbient temp-20…85oCTemperature driftSuperior to ±0.2%F S/oCStabilitysuperior to 0.2%F·S for 1 yearPower supply12…36VDCLoad resistance0~600ΩProof pressure150%F·SStorage temp-40…125oCCan modify the range of transmitter with screenProduct FeaturesTwo-wire working mode: power supply, output two-wire systemStability: annual drift ≤ 0.2%F-SLarge measuring range: 0~10kPa and above; Negative range can be customized.Calibrated according to the full scale of the sensor.
