Radar Level Transmitter is Designed for Saturated Steam Applications
The MT2000 Wave Guide Model C9P81 makes measurements using guided-wave radar — a waveguide directs the microwave pulses, eliminating the beam divergence problems common to conventional non-contact radar transmitters. Because operation does not depend on fluid density, readings do not fluctuate with shifts in the specific gravity of the fluid and are not subject to variations in dielectric constants. The C9P81 features an alumina ceramic insulator that allows accurate and reliable measurements up to 2,000 psi (138 bar) at 635°F (335°C).

Sensor Module Detects Combustible Gases
The Model 5100-28 IR combustible gas sensor module monitors for methane and can be configured to monitor for a wide range of other gases in either 0–100% LEL range or a 1–100% by volume range. Features include digital display of gas concentration, one-person menubased calibration, and alarm relays for high, low and trouble alarms.

Multi-Gas Detector Provides
A single “Mode” button controls all of the MultiPro’s operations. The unit provides a calibration- due reminder and sensor-span reserve indicators for predictive maintenance. Dual-channel sensor technology allows the instrument to provide up to four channels of detection with just three sensors, all of which are field-replaceable. It includes O2 and LEL sensors, and a choice of either a dedicated CO or H2S sensor, or a sensor that measures both CO and H2S simultaneously. The MultiPro offers visual and audible notification for warning, danger, short-term exposure limit (STEL) and time-weighted average (TWA) alarms, and it stores maximum and average readings as well as time and duration for up to 20 events.

Multi-Function Humidity Transmitters Come in Digital and Analog Versions
Packaged in a rugged housing, the HT-737 advanced digital transmitter measures relative humidity, temperature, dew point and absolute humidity. It features a programmable controller, digital zero and span adjustment, and RS-232 or RS-485 output capability. The HT-761 analog version provides a linear 0–1 VDC or 1–10 VDC output of ambient relative humidity and temperature over the range of 32–176°F.

Measure Level with this Pressure Transmitter
The HYD submersible pressure transmitter offers highprecision hydrostatic level measurement for pressures from 3.3 ft w.c. (1.5 psi). It features a compact stainlesssteel housing with a flushmounted laser-welded diaphragm suitable for use with viscous media. The temperature-compensated transmitter has a special cable with an integrated vent tube that provides a true reference pressure to the sensor element, eliminating errors due to barometric pressure changes. The unit provides a 4–20-mA output signal, and achieves an excellent long-term stability of <± 0.1%FSS/yr.

Magnetic Flowmeter Features Improved Diagnostics
Retaining all the features and functions of earlier Admag flowmeters, the Admag AXF magnetic flowmeter offers new diagnostics to detect electrode coating. By constantly monitoring the change in the impedance of the electrode circuit due to the build-up of insulating coatings, the AXF converter will display four different levels of coating and provide an alarm function. Optional replaceable electrodes make maintenance and cleaning easier, because the user can rely on the new predictive diagnostics to monitor the status of the electrodes and then remove them for cleaning when necessary.
