RTX 1000A (Analogue) Pressure Transmitters

 

RTX 1000A (Analogue) pressure transmitters offer a cost effective solution to gauge and absolute pressure measurement with outstanding performance and conventional 4-20mA output with 10:1 turndown.

 

The RTX 1000H (HART) Series provides a choice of user rangeable pressure transmitters with HART® digital signal superimposed (RTX 1000 H). Offering turndowns up to 100:1 and ranging from 0.3 psi to 20,000 psi, the RTX 1000 covers the widest range of gauge and absolute pressure applications available on the market.

Features

  • URL’s from 10 psi to 20,000 psi
  • 100:1 rangeability
  • ‘Best in class’ performance
  • Hastelloy C diaphragm supplied as standard
  • Aluminum or stainless electronics housing
  • NAMUR compliant alarm outputs

Applications

The optional stainless steel electronics housing is cost-effective for applications such as offshore oil and gas or in hygienic environments such as food and beverage or pharmaceutical facilities.

The Aluminium Bronze end caps ensure free-running threads throughout the life of the transmitter.

Specifications

Pressure Measurement

Pressure Ranges Standard ranges which can be calibrated to any acceptable intermediate span/pressure unit:-
0 - 700mbar gauge or absolute
0 - 2 bar gauge or absolute
0 - 7 bar gauge or absolute
0 - 20 bar gauge or absolute
0 - 70 bar gauge or absolute
0 - 200 bar sealed gauge or absolute
0 - 700 bar sealed gauge or absolute
0 - 1400 bar sealed gauge or absolute
Range Adjustment Full 4 - 20mA output change for any user span setting within Upper Range Limit (URL) as below:
RTX 1000H: 1 - 100% URL
RTX 1000A: 10 - 100% URL
e.g. RTX 1000 H:- 2 bar device can be adjusted down to a span of 0.02 bar (100:1 down ranging)
Zero offset - for absolute configurations:
RTX 1000H: 0 - 99% URL
RTX 1000A: 0 - 90% URL
For gauge configuration, the zero (4mA) output can be set anywhere within the range below:
RTX 1000H: -1 bar to 99% URL
RTX 1000A: -1 bar* to 90% URL
(* -700 mbar for 700 mbar range)
e.g. 2 bar gauge device can be set 4-20mA for -1 to 1 bar. Down ranged to 0.2 bar span, 4-20mA
can be set anywhere within range to a zero offset of 1.8 bar, e.g. calibrated range of 1.8 bar to 2 bar.
Overpressure Rated pressure can be exceeded by the following multiples without degrading performance:-
6 x URL for 700mbar range
4 x URL (140 bar max) ranges 2 bar to 70 bar
2 x URL (900 bar max) ranges 200 bar to 700 bar
2000 bar max for 1400 bar range
Pressure Containment High pressure application as below may damage sensor but process media leakage will not occur:-
10 x FS for 700mbar gauge range
6 x FS (200 bar max) ranges 2 bar to 70 bar gauge
200 bar for ranges up to 70 bar absolute
1400 bar for ranges 200/700 bar sealed gauge/abs
2100 bar for 1400 bar range sealed gauge/abs.
Process Media Any liquid, gas or vapour compatible with Hastelloy C276 diaphragm and 316 stainless steel or Hastelloy C276 body. NACE MR-01-75 compliant.
NB. 1400 bar range: compatible with Inconel 625.
Output Current 4 - 20mA (2 wire configuration).
RTX 1000 H:- HART® digital signal superimposed.
Failure Mode (NAMUR NE 43 compliant)

If pressure is applied outside upper or lower range settings, output saturates at Under Range 3.8 mA Over Range 20.5mA. Display flashes out of range.

In the event of failure, output will be driven to 21mA (user configurable) and, if
fitted, the display will confirm the alarm status.
