The pressure sensor 33X achieves an extremely high accuracy of 0.05% full scale (FS) in the temperature range of 10 to 40°C through a mathematical correction method. An additional option for high precision of 0.01% FS is also available. In addition to a digital RS485 interface, analog current or voltage outputs can be obtained. 【Features】 - Accuracy of ±0.05% FS in the temperature range of 10 to 40°C - Standard dual outputs of digital RS485 and analog output - Analog output can be range-adjusted via digital RS485 - Available in barometric range type (800–1200 hPa) and differential pressure range type (from 0–30 kPa to 0–3 MPa) - Temperature range of -20 to 125°C (optional -40°C also available) - Excellent long-term stability 【Technology】 - Piezo-resistive pressure sensor - Correction technology using a mathematical model to produce accurate pressure values

• Pressure

Ideal for measuring pulsations and unsteady behavior with a bandwidth of 50 kHz, temperature-resistant up to 180°C, built-in amplifier (0-10V output) high-precision pressure sensor.

The ultra-high-speed pressure sensor M5HB can measure not only static pressure but also pressure changes within a bandwidth of 0 to 50 kHz. This is achieved by the digital circuit continuously adjusting the analog signal in real-time, with an output of 0 to 10V. The compact sensor head with M5 fine thread can be used at temperatures up to 180°C. It has a pressure resistance of up to five times the measurement range and is an excellent model for vibration resistance. 【Features】 - Temperature resistance of the sensor head: 180°C - Output is an analog signal of 0 to 10V (with built-in amplifier) - Wide temperature compensation range: -20 to 125°C or -40 to 180°C - Bandwidth of 50kHz, ideal for measuring pulsations and unsteady behavior - Resistant to impacts and vibrations - Compact design, pressure connection is M5×0.5 fine thread

• Pressure

±0.05% accuracy / Digital pressure gauge with logging function, explosion-proof type available

The high-precision digital pressure gauge LEO Record can record pressure and temperature for extended periods thanks to its memory function. The data logger can be connected to a computer via an RS485 interface for reading the recorded data. The current pressure value can be displayed in multiple pressure units. It is powered by a 3.6V lithium battery. An intrinsically safe explosion-proof type is also available. 【Features】 - Can record pressure and temperature for long periods - High precision (±0.05%FS @ 20–25 °C) - Ultra-low power consumption, long battery life - Can display in various pressure units (bar, mbar, hPa, kPa, MPa, PSI, kg/cm2, cmH2O, mH2O, etc.) - Zero point calibration via button - Intrinsically safe explosion-proof type available
