Description
For application of sweet (H
composition of the gas must be above the upper explosive limit.
Chilled-mirror technique.
2 °C per minute (typical cooling rate), with cycle time typically
20–30 minutes.
Actual response time will vary based on process conditions, the
cooling rate, pressure, and the temperature of the last dewpoint.
Hydrocarbon Dewpoint temperature:
±1 °C (±2 °F) with laboratory-grade propane.
Accuracy is determined by using pure propane and comparing the
measured results with that from published vapor pressure data for
propane.
±0.4 °C (±0.7 °F)
±0.1 °C (±0.2 °F)
This is for the stability of temperature measurement only.

Analog Outputs
4 isolated 4–20 mADC self-powered (standard) or loop powered
(optional).
Self-Powered:
Configured as a 2-wire transmitter,
compatible with a loop impedance of
0–1000 ohms.
Loop-Powered:
1500 Vrms isolated analog output
configured as a 2-wire transmitter. An
external power supply (15–30 VDC) capable
of supplying 25 mA per loop is required
(supplied by customer). When 30 VDC is
supplied, the maximum loop impedance is
1000 ohms.
6 independent sets of SPDT Form C, dry (potential free) relay
contacts, 24 VDC, 0.5 A maximum
Digital Communication
Local Service Port:
RS-232
Remote Service Port:
