Device  is  designed  for  measurement  of  atmospheric  pressure  at  hPa,  PSI,  inHg,  mBar, 

oz/in

O and kPa. It is possible to set pressure correction for altitude (offset). Device 

setting  is  provided  by  user’s  software,  see  latter.  Device  T2314  communicate  via  link  RS232, 
device  T2414  via  link RS485.  Supported  communication  protocols  are  Modbus  RTU,  protocol 
compatible  with  standard  Advantech-ADAM,  ARION  and  communication  with  HWg–Poseidon 
devices.  Devices  are  preset  from  manufacturer  to  Modbus  RTU  communication  protocol.  If  you 
would like to use different communication protocol then Modbus RTU, it is necessary preset them 
through user’s software – see latter. Pressure sensor is placed inside the electronic case. Measured 
value is optionally shown on LCD display. Display can be switched OFF too. 

 

Use  user’s  software  TSensor  for  setting  of  all  device  parameters  (recommended). 

It is free  to  download  at

.  It  supports  make  the  adjustment  of  the  device 

too.  This procedure  is  described  at  file  „

Calibration  manual.pdf

“  which  is  installed  commonly 

with the software.  Change  of  some  parameters  is  possible  to  do  without  user’s  software 
with Windows  hyperterminal  (change  of  communication  protocol,  its  parameters,  LCD  display 
setting).  It  is  described in file “

Description  of  communication  protocols  of  Txxxx series

” which is 

free to download at the same address. 
 

Transmitter  version  T

xxxx

L

  with  watertight  male  connector  instead  of  a  cable  gland 

(RS232) or glands (RS485) is designed for easy connection/disconnection of communication cable. 
Male Lumberg connector RSFM4 has protection IP67. 
 

Models  marked  T

xxxx

are  non-standard  versions  of  the  transmitters.  Description  is  not 

included in this manual. 
 

Please read instruction manual before the first device connection.
