Si792 security explosive transmitter

The two-wire intrinsically safe explosion-proof transmitter can be connected to the Hach GLI sensor
● pH differential or composite pH/ORP sensor
GLI 3400 series inductive conductivity sensor
GLI 3700 series non-polar conductivity sensor (concentration analyzer)

Multiple communication protocols
The Si792 transmitter has digital communication function, which can easily connect to the selected communication network, including HART? 、 PROFIBUS PA、 Or Foundation? Optional protocols such as Fieldbus.

Application of different explosion-proof levels
Class I, Division 2 (C I, D 2), only equipped with HART protocol;
● Class I, Division 1 (C I, D 1), intrinsically safe, equipped with HART,
PROFIBUS PA or Foundation Fieldbus protocol. Certified by FM, CSA, and ATEX professional organizations.

Sensor self diagnosis
The Si792 transmitter can perform self diagnosis and sensor monitoring, such as monitoring potential asymmetry, electrode slope, response time, cable status, glass electrode status information, etc.

The sensor is in good condition. The sensor condition is average and needs to be replaced as soon as possible. Zero and slope values cannot guarantee correct calibration or Sensor malfunction or breakage.

By setting, different password protections can be set:
● Sensor calibration
● Transmitter settings
● Administrator function
