• HF3. Technical Description

HF4 - Industrial humidity and temperature sensors are designed to transmit analog and digital output signals to user systems. The sensor consists of a measuring unit and a probe rigidly fixed to the housing. Versions with analog output signals 0...20 mA, 4...20 mA, 0...1V, 0...5V, 0...10V and digital outputs RS-485 / USB/LAN/WLAN / MODBUS (ASCII) are available. Each of the two analog outputs can be assigned an individual scale and one of the humidity conversion units (for example, instead of relative humidity, the dew point temperature can be set, etc.).

HF456 (HF4 digital) - Industrial humidity and temperature sensors are designed to transmit digital output signals to user systems. The sensor consists of a measuring unit and a probe rigidly fixed to the housing. Versions with digital outputs RS-485 / USB/ LAN/WLAN / MODBUS (ASCII) are available.

• HF456. Technical description

HF5 - Industrial humidity and temperature sensors are designed to transmit analog and digital output signals to user systems. The sensor consists of a measuring unit and a removable interchangeable humidity and temperature probe connected by an extension cable. Versions with analog output signals 0...20 mA, 4...20 mA, 0...1V, 0...5V, 0...10V and digital outputs RS-485 / USB / LAN /WLAN / PoE (Modus B) are available. Each of the two analog outputs can be assigned an individual scale and one of the humidity conversion units (for example, instead of relative humidity, the dew point temperature can be set, etc.).

• HF5. Technical Description

HF556 (HF5 digital) - Industrial humidity and temperature sensors are designed to transmit digital output signals to user systems. The sensor consists of a measuring unit and a removable interchangeable humidity and temperature probe connected by an extension cable. Versions with RS-485 / USB/LAN/WLAN/PoE digital outputs are available.

• HF556. Technical description

HF5-Ex - Intrinsically safe industrial humidity and temperature sensors are designed for installation in explosive zones Zone 0/20 (probe only) or Zone 1/21 (probe with converter) and transmission of analog output signals 4...20 mA to the user's systems. The sensor consists of a measuring unit and a removable interchangeable humidity and temperature probe connected by an extension cable. The sensor is made in a durable aluminum housing, the humidity and temperature probe is made in a stainless steel housing. The sensors do not require an intrinsically safe power supply.

Scope of application: Automated control and management systems of nuclear power plants.

• HF5-Ex. Technical description

HF7 - Industrial humidity and temperature sensors are designed to transmit analog output signals to user systems. The sensor consists of a measuring unit and a probe rigidly fixed to the housing, or connected by an extension cable of 2 meters. Available versions with output signals 0...20 mA, 4...20 mA, 0...1V, 0...5V, 0...10V. Each of the two analog outputs can be assigned an individual scale and one of the humidity conversion units (for example, instead of relative humidity, the dew point temperature can be set, etc.). The sensor housing is made of aluminum, the probe is made of steel, or heat-resistant PPS plastic. One of 3 types of protective filters is installed on the sensors: steel mesh, Teflon, porous steel.

• HF7. Technical Description

HF8 - Industrial humidity and temperature sensors are designed to transmit digital and analog output signals to the user's systems, as well as to control external devices using 4 programmable relays. The sensor consists of a measuring unit and external probes rigidly fixed to the housing, or connected by extension cables up to 5 meters long. Available versions with output signals 0...20 mA, 4...20 mA, 0...1V, 0...5V, 0...10V. Each of the two analog outputs can be assigned an individual scale and one of the humidity conversion units (for example, instead of relative humidity, the dew point temperature can be set, etc.). The built-in 4 relays are controlled by signals from two humidity and temperature probes. 2 logical signal inputs allow you to control the on/off of devices. The sensor housing is made of aluminum, the probe is made of steel or heat-resistant PPS plastic. One of 3 types of protective filters is installed on the sensors: steel mesh, Teflon, porous steel.
