CHT-IFP 1865 Series
(CHT) Ceramic Hybrid Infusion Pump
mV Compensated, Constant Voltage, Infusion Pump Sensor
About the CHT-IFP 1865
Advanced Sensor Ceramic Hybrid Technology (CHT) IFP Series is
a temperature compensated, mV output, sensor designed for
medical OEMs in either peristaltic or syringe pump
applications.
The INFusion Pump (IFP) sensor is specifically designed for
occlusions sensing in peristaltic pumps where the durable
silicon rubber diaphragm can withstand the mechanical forces
of rotating fingers applied through a flexible membrane.
The design of force/pressure transducers can also be used with
other medical dispensing devices, such as syringe pumps, to
improve safety and accuracy.
The sensor incorporates a silicon MEMS sense element that is
individually tested and calibrated through laser trimming of the
thick film resistors providing a high-level output at constant
current or voltage. The sensor durable white diaphragm is
precision dispense ensuring output at low pressures.
