HD50CR is a relative or differential low pressure transmitter and data logger designed for wall flush-mounting. Measuring range ±125 Pa. A silicon piezoresistive sensor with high accuracy and temperature compensation is used, which allows excellent linearity, repeatability and stability over the time. The auto-zeroing feature allows stable measurements over the time without the need to recalibrate.

An input for an optional relative humidity and temperature combined probe is provided. The absolute humidity, the Dew Point and the wet bulb temperature are calculated. Three 0…5/10 V and 0/4…20 mA analog outputs and a digital RS485 output with “Slave” Modbus-RTU protocol for connecting the instrument to a network of sensors are available.

The electroluminescent display has an inattinic red protection. The front keyboard allows scrolling the real time measurements and configuring the instrument.

The instrument can be connected to a local network via the Ethernet interface (optionally Wi-Fi, on request). The simultaneous operation of two communication protocols (proprietary and Modbus TCP/IP) is possible. The instrument manages up to 10 “TCP/IP Client” simultaneously. If the local network is connected to Internet, the data can be regularly sent to an FTP address, to the Cloud and via e-mail.

Equipped with a USB port with mini-USB connector for the direct connection to a PC. For each detected quantity, two alarm thresholds can be set by the user. Exceeding a threshold is signaled acoustically, by means of the internal buzzer, visually, by lighting the alarm LEDs on the front panel (only for the three measurements associated with the analog outputs), and remotely, by sending alarm e-mails. An alarm hysteresis and a delay in the generation of the alarm can be configured for each detected quantity.

Thanks to the integrated web server, you can configure the instrument and view the real time measurements from any PC, tablet or smartphone connected to the same local network of the instrument by simply using a web browser.

The PC software HD35AP-S allows configuring the instrument, viewing the real time measurements, downloading and viewing the data into a database. The HD35AP-S software allows connecting one instrument at a time. If there are several HD50CR instruments in the local network, the PC software HDServer1 allows detecting automatically all the instruments connected to the network and the simultaneous connection to all the instruments, entering the data received by the instruments into a database, viewing the data in the database and configuring some basic parameters of the devices (alarms, logging interval, …). The HD35AP-CFR21 software option (available with both HD35AP-S and HDServer1) allows the protection of recorded data and configuration in response to FDA 21 CFR part 11 recommendations. The internal clock can be regularly synchronized with a NIST reference server. Brushed stainless steel front panel. The instrument is supplied factory calibrated.
