Solutions for tomorrow’s sensing applications...TodayTM
The Model P155 pressure transducer
is specifically designed for pressure
measurements 0-15 through 0-1000
PSI. The stainless steel housing
and ceramic diaphragm withstand
exposure to compatible liquid and
gaseous media.
Excited by 5 Vdc, the P155 provides
a 0.5 through 4.5 Vdc linear signal
output proportional to pressure.
Typical applications include steam
sterilizers, laboratory test apparatus,
marine, agricultural chemical equipment,
refrigeration and HVAC systems,
hydraulic systems, gas tank pressure
monitoring, level measurement, test
equipment, pressure measurement of
aggressive fluids, injection molding,
atmospheric pressure, spraying
equipment, printing pressures,
coolant pressures, weighing
equipment and off-shore drilling rigs.
Key to the high performance of
the P155 pressure transducer
is KavlicoÕs ceramic, variable
capacitance sensing element with
ASIC and hybrid circuit for reliable
signal conditioning and maximum
electronic integration. This same
technology is successfully used by
Kavlico for automotive, diesel engine,
medical and HVAC applications.
Millions of Kavlico sensors are in
use worldwide.
KavlicoÕs sophisticated manufacturing practices have
earned the highest quality awards from its customers.
As an ISO 9001 registered company, Kavlico is
committed to total customer satisfaction. Each and every
pressure sensor is tested for conformance to its
applicable specifications prior to shipment.
OPERATION
APPLICATIONS
The design of application specific sensors to meet
demanding OEM requirements is KavlicoÕs primary
function. Using the broadest range of sensing
technologies, we provide components with greater
EMI and over-voltage protection. Solid state switching
functions and voltage regulators can be built into Kavlico
sensors for use with unregulated power.

Warranty: Kavlico warrants that its products will be free from defective materials
and workmanship for a period of one (1) year from date of delivery to the original
purchaser and that its products will conform to KavlicoÕs specifications or standards. Any
product found to be defective will be replaced or repaired at the sole option of Kavlico.
Note: Kavlico reserves the right to change its specifications at any time without notice.
Kavlico is not expert in the customerÕs technical field and therefore does not warrant
the suitability of its product for the application selected by the customer.
Kavlico products are manufactured or covered by one or more of the following patents:

The case of this device is not connected to the ground lead.
Three lead wires Red (Supply Voltage), Black (Ground), Green
(Output) provide electrical connection to power and instrumenta-
tion. Teflon tape or suitable sealant may be used on NPT pressure
fittings in suitable amounts so as not to interfere with a good ground
connection to chassis.
