The VPEL series differential pressure transmitters are developed for measuring water (glycol) pressure differences in cooling systems and central heating installations. The VPEL series is optionally available with a display.

The HML series carbon monoxide transmitters are designed for detecting carbon monoxide in underground parking garages. The sensing element is an environmentally friendly electrochemical cell with a long service life, excellent long-term stability, and high accuracy. Since the sensor is heated, the transmitter also operates reliably at very low temperatures down to -30°C. The HML series feature…

The PEL series differential pressure transmitters offer high reliability. They are suitable for building automation applications where extra accuracy and stability are required. Using jumpers, the measuring range can easily be adjusted in the field. In addition to filter monitoring and belt break detection, the PEL series is also highly suitable for measuring very low differential pressures, s…

The KPEL series combines two differential pressure measurements in a single transmitter. These dual differential pressure transmitters can be used to monitor two filters with one device. The measuring range can be selected in the field from 100 Pa to 2500 Pa. Optional versions are available with a display and/or Modbus communication.

The Produal PEL8K series consists of straightforward differential pressure transmitters for measuring static pressure and fan pressure in air ducts. In the field, the measuring range can be set from 1000 to 8000 Pa. Optional versions are available with a display and/or Modbus communication.

The VPL series pressure transmitters are developed for measuring water pressure in cooling systems and central heating installations. The VPL series is optionally available with a display.

The Produal PEL2500 series consists of straightforward differential pressure transmitters for filter monitoring and measuring static pressures in air ducts. In the field, the measuring range can be set to 100, 200, 500, 1000, 1500, 2000, or 2500 Pa. Optional versions are available with a display and/or Modbus communication.

The Produal PEL1000 series consists of straightforward differential pressure transmitters for filter monitoring and measuring static pressures in air ducts. In the field, the measuring range can be set to 500 or 1000 Pa. Optional versions are available with a display and/or Modbus communication.

The KA10 is a condensation switch specially developed for cooling systems, such as chilled ceilings. The KA10 features a 0–10V output for reading the level of condensation via a building management system (BMS). In addition, it has a relay contact output for connection to the HLS44 series room controllers. This allows the cooling control to be interrupted immediately when condensation forms in…

The VVK2 series leak detection switches detect leaks in cooling systems and central heating installations in buildings. The VVK2 can be mounted on a DIN rail and provides an alarm contact when a leak is detected. Leak detection sensors can be selected separately, with versions available for floor and pipe mounting. Multiple leak detection sensors can be connected in parallel.

The LPH10 series leak detection switches detect leaks in cooling systems and central heating installations in buildings. The LPH10 can be mounted on the wall in a room and provides an alarm contact when a leak is detected. In addition to the relay signal, an indicator light will turn on and an audible alarm will sound. Leak detection sensors can be selected separately, with versions available…

The PLT24 series is a motion sensor for mounting on a wall or under a ceiling. The PLT24 operates on a 24 Volt power supply. The contact output can be used as input for a building management system or directly for a room controller. Motion sensors can generate significant energy savings by ensuring that ventilation or lighting is only activated when movement is detected in a room.

The PLT12 series is a motion sensor for mounting on a wall or under a ceiling. The PLT12 operates on a 12 Volt power supply. The contact output can be used as input for a building management system or directly for a room controller. Motion sensors can generate significant energy savings by ensuring that ventilation or lighting is only activated when movement is detected in a room.

The VVA and VVN series leak detection sensors are compatible with the LPH10 and VVK2 series leak detection switches. Various versions are available for floor mounting or installation under a water pipe. By mounting the sensor beneath a cooling pipe, condensation can also be detected.

The KEK1 is a simple passive condensation sensor. The sensor has a resistive output that provides a signal of approximately 10kOhm when condensation forms. It can be connected to the R102 and RS102 room controllers. The KEK1 sensor then ensures that the control of a chilled ceiling is interrupted when condensation forms on the cooling system.
