ES Systems S.A.  

ES Systems has developed ESRF-ESF, an inline gas flow sensor, based on the hot-film anemometer principle for mass gas flow measurements.

ESRF-ESF is one of the few gas flow sensors featuring bidirectional gas flow sensing of up to ±300 ln/min with a total error band of < 1.25% RD. ESRF-ESF gas flow sensors provide calibrated and temperature compensated output on an SPI, I2C bus or analog output making them plug & play for direct interfacing to low voltage MCUs and systems. The user is provided with a multitude of interface and output options so that the right sensor configuration can be selected based on the specific requirements for each application.

Due to the compact design, and versatility, ESRF-ESF gas flow sensors are ideal for medical, process & pharmaceutical equipment where high accuracy and reliability are of the essence.

Calibration gas is air but other non-aggressive gases are available upon request.

ES Systems has developed ESRF-HF, a family of insertion gas flow transmitters, based on the hot-film anemometer principle for mass gas flow measurements.

The ESRF-HF is a family of mass flow transmitters which enable fast and accurate measurements of gas flow over a wide dynamic range. Each transmitter integrates a MEMS flow sensor and readout electronics inside a housing with very small form factor made from stainless steel. The duty pressure of the flow transmitter is 11bar. All measurement data are fully calibrated, and temperature compensated on board, leading to a reduced temperature coefficient and high measurement accuracy.

The standard system provides analog signal output, with excellent repeatability and hysteresis combined with good resolution. Calibration gas is air, but other non-aggressive gases can be also available upon request.

The compact size of the ESRF-HF flow transmitters combined with the ruggedized stainless-steel housing makes them ideal for use in industrial applications within confined spaces. For easier handling and mounting, a series of in-line pipe adaptors (Ø20, Ø25, Ø32) is also available upon request.

ES Systems has developed a series of board mountable pressure sensors targeting a variety of markets requiring high resolution and accuracy for gas pressure measurements. The ESCP-BMS1 is a silicon capacitive pressure sensor with state-of-the-art performance and exceptional quality. The MEMS pressure sensor die is underpinned by ES’ innovative SOI-surface micromachining technology.

ESCP-BMS1 is an absolute, gauge or differential pressure sensor of ultra-high resolution with analog (0-3,3V), SPI or I2C interface. The output is fully calibrated, and temperature compensated based on the internal temperature sensor and the factory calibration coefficients which are stored in the embedded memory. The sensor is ready to be installed directly to the end system without further processing with medical, HVAC, industrial, commercial & automotive applications. The total error including repeatability, hysteresis, non-linearity, thermal offset and calibration error between 0°C and 60°C is better than 0.25% FS.

Different power modes are available enabling low power operation. The sensor can be configured to provide both high accuracy 32-bit pressure and temperature outputs.
