Harshmax was born from the
experience of Laserpoint’s Optical
Sensor Lab.
The idea is to apply the criteria and
technologies of laser measurement
to new areas, with the objective to
start a new line of research and
development focused on the
creation of optical sensors able
to measure physical parameters –
such as pressure – using laser
technologies and fiber optics.

FEATURES AND BENEFITS
Passive head
No electronics inside the sensor head for better reliability. Sensor head is just made of stainless steel and optical fiber, all suitable for operation in HARSH environments with high temperature and high-pressure conditions (up to 1 kBar, up to 300°C). Insensitive to Electro-Magnetic Interference (EMI).
Remote Electronics
An Optical Fiber is used to transmit the pressure signal far from the HARSH environments such as extrusion machines. Electronics can be placed in a safe distance up to dozens of kilometers from the sensor head.
Patented
(granted in US, Canada, Europe, Brazil, China, Japan)
Pressure measurements performed by optical means without contact between internal mechanical parts as it happens in piezoelectric sensors: no mechanical stress for superior reliability.
Fully compatible
Perfectly replaceable to all existing sensors without the need for any intervention.
Lower Maintenance Cost
Tick deformable pressure sensing diaphragm allows for longer operating lifetime. Absence of toxic materials in the sensor head guarantees no contamination in the extrusion chamber. No need for electronics replacement when changing the sensor head.
Eco-friendly
Fully RoHS compliant, unique in the market. No need for mercury, oil or other toxic elements, typically found in piezoelectric sensors.
TECHNOLOGY HIGHLIGHTS
A specific laser welding manufacturing
process has been developed for the sensor’s
head in order to provide a hermetic junction
between the membrane and the body of the
sensor.
Dedicated test bench has been created to
test all the sensors at the highest
temperatures and pressures levels.
HARSHMAX shows very good linearity
between pressure and no presence of any
hysteresis.
Excellence in Fiber splicing and micro-optics
alignment is crucial in the
development of this new product and is
fully guaranteed by more than 30 years of
Laserpoint’s experience in laser technology.
