ENCLOSURE DESIGNS BOOST ENERGY SAVINGS UP TO 75% Rittal Systems has introduced Blue e+ IoT-enabled air conditioners and climate control systems said to help decrease enclosure energy costs by up to 75% while enhancing efficiency and ROI, both in industrial as well as IT scenarios. The company offers climate audits through it its experts, as well as various Climate Control C Configuration software tools. Stainless-steel vvariants of the Blue e+ cooling unit series ((protection category IP55) are suitable for dem manding environmental conditions, the comp pany says. Enclosure heaters regulate relative h humidity, prevent temperatures from dropp ping below the dew point, and stop condensation forming inside the enclosure.

The LevelMaster Capacitive Sensor from Rechner is said to be a high-performance sensor designed to solve applications with highly conductive or viscous products such as ketchup or honey. The sensor has no moving parts and accurate level control can be accomplished with w either digital or analog (4 to 20 mA) output. The T LED is a 2-colour device for viewing of operation status. The onboard electronics includes Easy Teach by b Wire (ETW) for simple and efficient set up, the company c says. If EHEDG (European Hygienic Engineering n & Design Group) is required, the company is said to have the appropriate mounting hardware. The T housing is IP67, IP69K and is designed for clean ŝŶ Ŷ ƉůĂĐĞ ; /W ϭϮϭȗ Ϳ͘ tĂƚĐŚ ǀŝĚĞŽ ĚĞŵŽŶƐƚƌĂƚŝŽŶ Ăƚ www.cpec.news/z7j. w

Orange Research differential pressure gauges from Cameron Instruments are designed to measure the difference in pressure between two points in a system and present the resultant differential pressure directly on a single gauge dial. A magnetic movement allows the simultaneous sensing of both pressures while completely isolating the differential pressure gauge function from the pressure chamber without the use of mechanical seals. Unlike ordinary pressure gauges, these differential pressure (DP) gauges are said to indicate small values of differential pressure even when used at high line pressures. Units are supplied with reed switches or relays to initiate alarms, activate other equipment, or shut the system down. Two switches are installed when high and low limit control is desired. Orange Research has also developed a series of differential pressure transmitters with the ability to transmit data signals. The microprocessor-based instruments are equipped with Hall Effect sensors that convert the differential pressure gauges' normal magnetic movements into electric signals. After processing, the DP gauge units provide analog output for remote location monitoring.

The Arjay Engineering 2852-DPM dry pump monitor and phase detector uses capacitance technology with what is said to be an ingenious non-intrusive design to protect pumps and equipment from damage due to dry or low volume conditions. The unit employs embedded sensing plates in a PVC wafer flange said to provide easy installation and no interference to the product flow. The sensor locks in on the capacitance field of the fluid passing through and accurately detects changes resulting from lower levels, different fluids, or changes of phase, to initiate an alarm, the company says. The monitor has UL, CAN/CSA, IEC and CE approvals and an Intrinsically Safe option.
