DATA SHEET
Fully Compensated TR Series
The TR Series
pressure transducer is a rugged, direct-media pressure
monitoring solution designed for today’s toughest pressure sensing environments.
The TR Series pressure transducer is a fully
compensated, amplified output pressure sensor
package combining Merit Sensor’s Sentium process
harsh media MEMS piezoresistive die with state-of-
the-art pressure sensor ASIC signal management.
The TR Series ”plug and play” design isolates onboard
electronics from system media through an inert eutectic
alloy solder bond of the MEMS pressure element to a
ceramic PCB substrate. Direct media pressure sensing
translates into excellent system design flexibility
leading to lower cost and ease of manufacture.
The TR Series is designed for air, liquid and gas harsh
media compatibility over a broad temperature range
from -40°C (-40°F) to 150°C (300°F) with a total error
band of less than 2.5%. The design includes a 4.7kohm
pull-up resistor, operates on a single 5.0VDC supply, and
requires no external components for proper operation.
Both gage and absolute pressure reference designs up
to 500 psi (35.5 bar) operating range are available.
