Product Description:

MTCS2601 silicon sensing die in SMD ceramic package

The MTCS2601 sensors consist of a micro-machined thermal conductivity sensor using four Ni-Pt resistors realized using MEMS technologies. The sensor is mounted in a miniature SMD package, available on tape and real. This MEMS TC sensor, combined with simple low power CMOS standard integrated circuits, is an excellent choice for size-critical leakage OEM detector or miniature vacuum gauge based on Pirani principle requiring ultra-low power consumption, long lifetime and no maintenance. Applications are primary pressure control in rough environment with power and size constraints, or detection in closed volume of gas leakage or moisture, or intrusion.

MTCS2601 Thermal Conductivity Sensor Applications
 Primary vacuum control following Pirani principle. This sensor is easily added within a pressure valve or directly in vacuum pipes or systems, such as small mechanical pumping systems, vacuum pumping machine and analytical instruments .
 Leakage miniature SMD sensor as control integrity of closed systems or instruments under dedicated pressure, able to
detect defect like corrosion or simply box opening (load cells; flywheel systems, Dewar)

MTCS2601 Thermal Conductivity Sensor Features
 Thermal conductivity sensor for primary vacuum measurement
 Silicon device in SMD ceramic package. Delivery in Tape & Reel
 Small dimension compatible with measurement in very small volume
 Low power consumption and short time constants
 Optimal sensitivity in the range 10-2 to 10+2 mbar. Possible extension in the range 10-4 to Patm
 Low cost for volume application
 Robust MEMS sensor following physical Pirani principle (hot wire) with no chemical reaction, based on gas thermal conductivity variation versus pressure
 Measuring range from 10-4 to 1000 mbar with excellent reproducibility
 Temperature compensated with excellent matching of compensation and heating resistors on the same silicon die
 Ultra small sensor gas volume such as < 0.1 cm3 
 Robust and long MTBF (> 30000 hs) due to physical resistive sensing principles
 Ultra-low power sensor consumption in operation (< 6 mW) due to the use of MEMS based micromachined silicon sensor with small heated mass.
 Ultra-fast response time < 50 ms
 Insensitive to mounting position
 Gold contact version upon request for corrosive gas environment
 Compatible with a simple constant excess temperature operation circuit
