Pressure and Temperature Measurement • Pressure Transmitters
Direct Mount Pressure Transmitters - Continued
266GDH/ADH DESCRIPTION
266GDH is a gauge pressure transmitter with direct mount seal suitable for measuring liquid, gas or steam pressure as well as liquid level in open tanks. Model 266GDH and 266ADH have the direct mount seal on the positive side, respectively with the reference at atmospheric or vacuum pressure, for gauge (266GDH) or absolute measurements (266ADH).
FEATURES • Base accuracy from 0.06 % of calibrated span D
• Reliable sensing system coupled with very latest digital technologies provides large turn down ratio up to 60:1
• Comprehensive sensor choice optimize in-use total performance and stability • Flexible configuration facilities provided locally via local LCD keypad • New TTG (Through-The-Glass) keypad technology allows quick and easy local configuration without opening the cover, even in explosion proof environments
• IEC 61508 certification version for SIL2 (1oo1) and SIL3 (1oo2) applications • PED compliance to sound engineering practice (SEP)
Pressure Transmitters with Remote Seal 266MRT/GRT/RRT/ART
DESCRIPTION Model 266MRT is a differential pressure transmitter with “multisensor technology” suitable for measuring liquid, gas or steam flow as well as level, pressure and density characterized by the remote seal construction. The unique combination of several sensor systems in a single device allows simultaneous measurement of differential pressure and absolute pressure. The sensor temperature and the absolute pressure are also used for eliminating environmental effects on the sensor. Models 266GRT or 266ART/266RRT for gauge pressure measurements with reference to atmospheric pressure or absolute pressure measurements with reference to vacuum are only equipped with one diaphragm seal.
FEATURES • Base accuracy from 0.04 % of calibrated span
• Proven sensor technology together with state-of-the-art digital technology large turn down ratio of up to 60:1
• Comprehensive selection of sensors optimized performance and stability • Flexible configuration options local configuration via keys on LCD indicator • New TTG (through-the-glass) key technology enables quick and easy local configuration without the need to open the cover - even in environments with explosion protection
• IEC 61508 certification for SIL2 (1oo1) and SIL3 (1oo2) applications • Full compliance with Pressure Equipment Directive (PED) category III
