Differential Pressure Transmitter

PDT102

Features

• In-place system calibration and

online monitoring without

disturbing process tubes with

optional process valve actuator

and test jacks

• Ultrathin profile ideally suited for

DIN rail mount reduces

installation and calibration costs

• High accuracy, two options;

0.25 % or 0.50 % of span

• Extremely robust MEMS silicon

sensor technology provides very

high accuracy, sensitivity, stability,

and durability

• Calibrations traceable to SI units

through national metrology

institutes or accredited calibration

laboratories

• Front side accessible zero and

span adjustment potentiometers

Vaisala Differential Pressure Transmitter PDT102 offers ultra low pressure

measurement for cleanroom control and monitoring applications.

Operating environment

Vaisala Differential Pressure Transmitter

PDT102 is a high performance instrument

designed primarily for life science and

high technology cleanroom applications.

The front panel includes zero and span

adjustment potentiometers for

convenient adjustment. The PDT102

transmitter is ideal for incorporating into

the Vaisala viewLinc Continuous

Monitoring System to measure and

monitor the critical environmental

parameters as required in regulated

environments.

Performance

PDT102 offers very high accuracy,

sensitivity and stability with two options

for accuracy, 0.25% or 0.50% of span

providing a highly reliable and

repeatable measurement. The sensor

uses a micro-machined, ultra-thin silicon

diaphragm which provides inherent

sensor repeatability and stability. The

sensor enables precise measurement and

control in high performance cleanrooms.

The PDT102 transmitter is available with

voltage output (3-wire) or current output

(2-wire).

Available options

Online monitoring of PDT102 is simple

using the optional process valve actuator

and the front access test jacks. The front

access test jacks provide online process

reference signal or calibration signal

without disconnecting power supply

wiring. Measurements can be made using

a standard multimeter.

Applications

PDT102 is designed for use in critical

monitoring of cleanrooms for

pharmaceutical, biotechnology, medical

device, and semiconductor controlled

manufacturing environments.
