TT HART

Thermal Instrument is the leading TT HART Manufacturer in India providing reliable solutions for accurate temperature measurement to process industry worldwide.

HART intelligent temperature transmitter module GLP248H is a hart transmitter module with high precision and high stability. It inherits most HART protocol commands and some custom command and is compatible with most of the ISA types Thermocouples and Resistance Temperature Detector signal transmission. This product uses 24 bits Σ-△ sampling chip, which can ensure high-precision measurement; Adopt anti surge and anti-reverse connection design to avoid mis installation and mis operation in engineering installation; Adopt enhanced software security design, including independent watchdog, low-voltage monitoring reset, multi task scheduling optimization and other functions. All imported components are used to ensure long service life and stability. The HART communication device can be used for configuration settings.

Routine tests:

a) Calibration Test
b) Transmitter Configuration
