The new DHS110 Heat Spy Series of compact, hand-held, noncontact infrared thermometers provides a completely portable, easy to use, cost-effective, and accurate means to measure surface temperatures in process or maintenance applications. Its temperature range is 0-850° F. (-18° to +450° C.).

Units are housed in a compact case measuring 6 by 2 by 1 in. thick (152 by 51 by 21 mm). Although small in overall size, the DHS110 features an easy-reading 1.5 in.(38 mm) diagonal LCD screen with large 3/8 in. (9.5 mm) digits. Display resolution is 1° in either °F. or °C. scale. A keypad-actuated backlight aids display visibility in low-light conditions.

Two models are offered: XL and XEL. Both come with a bright laser aiming beam, allowing precision targeting of surfaces to be measured. Laser use is on-off selectable. Power is supplied by one 9 v battery with a low-battery warning incorporated in the LCD. Both models respond in 500 ms, and measure through a range of 7-18 microns. A built-in hold function retains display values for 6 sec, enabling accurate reading observance and temperature recording.

In addition, the thermometer includes menu selection of a settable high-low alarm, adjustable emissivity, and memory access to the last recording observed. Menu selection also allows storage and recall of maximum, minimum, differential, and average temperatures.

New downhole caliper

New DigiCal downhole calipers convert mechanically recorded downhole information to e-data at the surface using digital scanning technology.

DigiCal combines high pressure, high temperature capabilities of Kinley Corp. calipers with advanced digital interpretation technology. This combination offers solutions in corrosion monitoring suited to oil field locations, especially extreme conditions and remote sites.

The caliper can be run to a maximum temperature of 600° F. and a maximum pressure of 20,000 psi with no limit of H2S or CO2 concentrations. The caliper does not suffer from any pressure or temperature related drift on sensors over recorded depths of as great as 30,000 ft, the company notes.

The mechanical nature of the caliper enables it to continuously record the position of each feeler simultaneously, rather than taking sequential spot readings of the position of each feeler in turn. The combination of the tool's temperature stability and continuous independent recording of each feeler aids accuracy and resolution.

The system enables mechanically recorded data in the tool to be converted into a more convenient electronic format as soon as the tool comes to the surface. The resulting e-data can then be processed using interpretation and visualization software to produce a corrosion log at the wellsite.

New pressure transmitter

The newest version SITRANS P, DSIII Series pressure transmitter incorporates software that provides diagnostic capabilities and simulation functionality.

Its diagnostic capabilities include high- or low-signal limit alarms; peak value registers that store the maximum and minimum values for pressure, sensor temperature, and electronics temperature; and two programmable watchdog timers that alert the operator when user-set maintenance and calibration times occur.

Local configuration of all operational parameters can be made using magnetic pushbuttons on the instrument, eliminating the need for programming devices, such as a handheld communicator or lap top computer with configuration software.

The transmitter's exclusive simulation capabilities provide for a complete signal simulation, from the input through to the output. A single technician can test the entire signal loop.

The transmitter is available for measuring pressure, absolute pressure, differential pressure, flow, or level. It can be specified with a number of exotic metal process diaphragms for use in aggressive process materials. The two-wire device provides a standard 4-20 ma output signal that is proportional to the input pressure. It can be programmed manually using three magnetic pushbuttons, or remotely using the HART or PROFIBUS PA protocols.

In addition to European CENELEC approvals, the DSIII is FM and CSA approved as intrinsically safe and explosionproof.
