  • 5335A - standard version for safe area or Ex zones 2 or 22
  • 5335D - ATEX, FM and IECEx certified for Ex zones 0, 1, 2, 20, 21 or 22.

PRetop 5337

is a small, 1 channel transmitter for sensor head installation, input can be: RTD, TC, linear resistance or mV. HART® communication by user selectable HART®5 or HART®7 protocols. When using PReset software, version 6.04 or later should be used.


PRetop 5437

is a small transmitter with single or true dual inputs with sensor redundancy and drift detection for sensor head installation, input can be: RTD, TC, potentiometer, linear resistance or bipolar mV. HART® communication with HART®7 protocol. Full assessment to IEC61508 : 2010 for use in SIL 2/3 applications. When using PReset software, version 8.02.1006 or later should be used. 


HART® files:

HART® bus files - DD & AMS, EDD and DTM - can be downloaded from page: prelectronics.com > Download > Software > Files for bus communication

Profibus® PA process bus connection

PRetop 5350

is a small, 1 channel, FISCO-certified digital transmitter for sensor head installation. Input can be RTD or TC sensor. Detailed product data available by clicking the type number.

  • 5350A - standard version for safe area or Ex zones 2 or 22
  • 5350B - ATEX, FM, CSA, IECEx, EAC-Ex, NEPSI and INMETRO certified for Ex zones 0, 1, 2, 20, 21 or 22.

Profibus® files - GSD and PDM - can be downloaded from page:
