Part of the SmartLine series of products, the SLN 700 from Honeywell Process Solutions is an 80 GHz non-contact radar level transmitter that is said to offer high accuracy and stability over a wide range of level applications. The series is also fully tested and compliant with Experion PKS. The SLN 700 utilizes Frequency Modulated Continuous Wave technology and has a measuring range up to 30 m (liquids) or 120 m (solids). Accuracy is to ±2 mm, with a process temperature range of -40° to 200°C, process pressure range of -1 to 25 bar, operating voltage 12 to 30 Vdc, and output signal choices of 4 to 20 mA and HART. For setup, the SmartLine Application and Validation Tool (AVT) allows users to specify their tank level application and options.

&>K d/E' K/> KE t d Z d,/ <E ^^ DKE/dKZ Arjay Engineering 4100-HCF series float sensor monitors employ HF capacitance for continuous monitoring of separated oil thickness on a water surface. A capacitance approach eliminates routine cleaning of the monitor systems, the company says. There are also no moving parts, while control and interface panel mounts are situated safely away from the process. The float sensor monitors the capacitance field of the water surface so that as the oil accumulates on the surface, the sensors capacitance changes. This interface signal is used to provide outputs, displays and relay control. The Arjay PMC (pulse module circuit) embedded within the float sensor converts the oil/water signals to a frequency pulse. This allows the controller to be safely mounted up to 1 km away from the sensor with virtually no loss to signal stability.

KNF has announced the UFK 1.1100 EX, a low pulsation, high flow liquid pump for HazLoc areas. The chemically resistant unit is said to provide performance required by oil and gas, extraction, and cooling circuit applications. The pump has a flow rate of up to 11.5 lpm, doubling the company’s previous maximum for HazLoc liquid diaphragm pumps. It has a single inlet and single outlet, with three diaphragms that are offset by 120° to each other and connected in parallel. Pulsation values below 200 mbar at the inlet and outlet can be achieved, with lower pulsation available with a damper. The unit provides continuous operation with up to 6 bar back pressure. Customers can choose between different protection levels with standard being C1, D1, Groups C&D single-phase AC motors.
The VEGAPULS 6X radar sensor from VEGA is said to handle many applications, whether the medium to be measured is liquid, solid, hot, cold, hazardous, or corrosive. The user specifies the operational parameters and process conditions, and the company configures and delivers the application-ready level measuring instrument. Using a custom radar chip, the level sensor now combines features of the company’s previous 80 GHz, 26 GHz, and 6 GHz sensors, such as VEGAPULS 64 and VEGAPULS 69, in one device. The instrument has Bluetooth for wireless adjustment with the VEGA Tools App and is equipped with SIL 2/3, as well as the latest IT cyber security standard IEC 62443-4-2.
