PP471

 MODULE FOR PRESSURE MEASUREMENT

 

The PP471 module acts as an interface between the TP704 and TP705 series Delta Ohm probes and 
the instrument.  
The TP704 series pressure probes have a 1/4” BSP threaded male connection and must be screwed 
in  the joint  where  you wish  to measure the pressure. The TP  705 series  have two Ø5 connections 
where  the  suitable  tubes  are  inserted  in  order  to  perform  the  desired  measurement.  Please  pay 
careful attention to the joint pressure sealing; use suitable gaskets and joints. A plastic cap protects 
the  threaded  connection.  Put  it  back  after  use  as  it  protects  the  pressure  cell  from  foreign  bodies. 

VERY IMPORTANT: ensure the probe's bottom scale is higher than the pressure that will be 
measured. In case this value is unknown, start by using higher-capacity probes. 

For  every  pressure  probe  a  range  of  overload  pressure  and  a  burst  pressure  are  declared: 
pressures  in  the  range  of  overload  pressure  don’t  cause  the  break  of  the  sensor  but  the 
declared  accuracy  can  be  overcome.  Pressure  over  the  stated  burst  pressure  may  break  the 
sensor. The application of higher pressures than the overload pressure limit, although lower 
than the burst pressure, may produce permanent damage to the probe (e.g. offset shift). Never 
exceed the stated burst pressure. 

Please see the technical characteristics of the probes on page 31.  

Upon  turning  on  the  instrument  automatically  detects  the  PP471  module.  The  probe's  type 
(absolute, relative or differential) and bottom scale value are detected even when the instrument is 
on.  If  no  logging  or  recording  operations  are  in  progress,  it  is  possible  to  change  the  probe 
connected to the module without turning the instrument off and on again.  

The measurement provided can be the instantaneous  or the peak value of the pressure: please see 
the PEAK key description on page 12. 
 

When the PP471 pressure module is connected, the internal sensor is disabled.

EMPERATURE PROBES

 

The  instrument  accepts  the  input  of  Platinum  temperature  probes  with  resistances  of  100Ω  and 
1000Ω, as well as Nickel temperature probes with a 1000Ω resistance. 
The Pt100 are connected to 4 wires, the Pt1000 and Ni1000 to 2 wires, with the excitation current 
chosen minimizing the sensor self-heating effects. 
All  probes  with  module are  calibrated  in  the  factory,  the  2  or  4-wire  probes  with  direct  input 

are 

checked for conformity with class A tolerance 

according to norm IEC751 - BS1904 - DIN43760.  

For  the  temperature  probes  without  SICRAM  module  (Pt100  4  wires,  Pt1000  and  Ni1000)  the 
model configuration is required (please see the description of the Probe Type menu on page 10). 
 
The °C or °F unit of measurement can be chosen for display, printing, and logging using the °C/°F-
ESC key. 
 

How to measure 

The  response  time  for  the  measurement  of  the  temperature  in 

air 

is  greatly  reduced  if  the  air  is 

moving.  If  the  air  is  still,  stir  the  probe.  Please  remember  that  the  response  times  in  any  case  are 
longer than those for liquid measurements. 
 
The temperature measurement by 

immersion

 is carried out by inserting the probe in the liquid for at 

least 60mm; the sensor is housed in the end part of the probe.
