Wireless Temperature Sensing System

Chromalox (Pittsburgh, PA) offers the IntelliTrace® Wireless system for heat trace applications in both ordinary and hazardous areas. The Chromalox temperature sensing system includes the IntelliTrace® ITAS or ITLS Series Heat Trace Control Panel and specific industrial wireless transmitters, which are paired with appropriate temperature sensors. The panel facilitates both wired and wireless temperature sensor inputs, and the touchscreen computer HMI distinguishes wireless circuits from wired ones. The IntelliTrace® Wireless system utilizes the Rosemount® 248 Wireless Temperature Transmitter, which may be pipe- or structure-mounted. The 248 transmitter is offered with either aluminum or polymer housing, and is available with or without a matching universal mounting bracket.

Sensor Diagnostics

The IP67-rated Allen-Bradley ArmorBlock IO-Link master from Rockwell Automation (Milwaukee, WI) allows manufacturers and industrial operators to access detailed sensor diagnostics in harsh operating environments. The device features event and process time-stamping capabilities for on-machine applications. The IO-Link master stores up to 40 timestamps of sensor events on each channel. Input timestamps of all sensor data also can be sent to the controller upon a change of state. The on-machine option requires only a single cable from the cabinet. The ArmorBlock IO-Link master includes connectivity for up to eight IO-Link sensors.

Transceiver

Mountain RF Sensors (Fort Lauderdale, FL) has announced the MtRF-7501 VHF/UHF Ground-to-Air Transceiver. The model supports Single Side Band (SSB), LSB, and USB modes. Featuring frequency ranges of 116–152 MHz (VHF) and 225–400 MHz (UHF), the Model MtRF- 7501 provides RF output of 25 Watts AM, 50 Watts FM, and 100 Watts on SSB. Housed in a 4U, 19-inch rackmount enclosure, the transceiver includes serial, USB, Ethernet, and remote display ports. The unit features a color touch screen standard, plus dedicated front panel controls for power, volume, squelch, tuning, and high/low power. The MtRF-7501 operates from 90–250 VAC line power or 24–32 VDC.

Lidar Sensor

Velodyne LiDAR (Morgan Hill, CA) has announced the Puck Hi-Res™ sensor. Expanding on the company’s VLP-16 Puck, a 16-channel, real-time 3D lidar sensor, Puck Hi-Res provides greater resolution in the captured 3D image. Puck Hi-Res retains the VLP- 16 Puck’s 360° horizontal field-of-view (FoV) and 100-meter range, but offers a 20° vertical field of view for a tighter channel distribution — 1.33° between channels instead of 2.00°. The real-time LiDAR sensor supports autonomous-vehicle, 3D-mapping, and surveillance industries and applications.

Pressure Sensor

SignalFire Wireless Telemetry (Hudson, MA) has introduced the Pressure Scout, a wireless pressure sensor that supports pressure monitoring and alarm reporting as part of the SignalFire Remote Sensing System. The first in a line of wireless integrated sensors, the Pressure Scout consists of a pressure sensor (integrated with a wireless node) and internal battery. Ideal applications for the device include well tubing and casing pressure monitoring, tank level monitoring, and compressor station status monitoring.

Magnetic Sensors

Wireless, non-contact magnetic sensors from Steute Industrial Controls (Ridgefield, CT), in the presence of their actuating magnet, send a unique, coded telegram to one or more compatible, easily-programmed receivers. The receiver accepts up to 10 discrete telegrams per channel. The magnetic devices, powered by a field-replaceable lithium battery, operate at 915 MHz (USA/Canada/Australia) or 868 MHz (Europe). Other features include sensing range of up to 30 mm; bidirectional communications with receiver; IP67 ingress protection rating; operating temperature range of -20 to + 65 °C; and a stainless-steel or glass-fiber reinforced plastic housing.

Pressure Sensors

All Sensors Corporation (Morgan Hill, CA) now offers the DLHR pressure sensor series. The new devices feature lower pressure ranges of 0.5 to 60 in H2O. All error compensation is performed internally by an advanced ASIC; no external calculation is required. The DLHR products include I2C or SPI output interfaces with 16/17/18-bit resolution. With the ability to operate at a low, variable supply voltage (from 1.68V to 3.6V), the DLHR Series supports portable applications, including medical devices associated with low pressure, remote sensing, spirometry, and industrial controls. Devices are available in 0.5, 1, 2, 5, 10, 20, 30, and 60 in H2O pressure.
