Model 1865 Series
Force/Pressure transducer
DESCRIPTION
The Model 1865 is a high-performance transducer specifically
designed to address the needs of medical and specialized
OEM applications. Offering laser-trimmed compensation, the
Model 1865 may be specified to operate with either a
constant current or voltage supply.
The Model 1865 employs a solid state piezoresistive pressure
transducer mounted in a plastic package. For applications
where force is applied by a flexible membrane to the sensor,
such as found in infusion pumps, the Model 1865’s precision
height silicone diaphragm provides long life and is a reliable
replacement for older force or load cell transducers. Utilizing
a silicon rubber diaphragm, the 1865 is compatible with some
liquid media applications.
The Model 1865 provides access to important safety features
in critical care medical instrumentation, such as occlusion
pressure or infiltration detection. The pressure data can
provide medical personnel with useful diagnostic information
regarding the condition of the patient’s circulatory system.
These force/pressure transducers can also be used with other
medical dispensing devices, such as syringe pumps, to
improve safety and accuracy.
May be operated in either current or voltage excitation, the
Model 1865’s output can be amplified or signal conditioned,
as required. The semiconductor-based sensor offers high
resolution using its Wheatstone Bridge strain gauge design.
The height of the unit’s patented, poured-in-place silicon
rubber diaphragm is controlled to ensure sensitivity to low
pressure. This diaphragm is bonded to a plastic header and
transmits force applied through a special silicone gel to the
diaphragm of a silicon peizoresistive die. The back of the die
is exposed to atmospheric pressure, which results in a gauge
pressure output.
TYPICAL APPLICATIONS
• Infusion pumps
• Anesthesia monitors
• Non-corrosive, nonpressurized media-level sensors
• Ventilation systems
• Blood pressure equipment
• Syringe pumps
• Drug delivery systems
