Rev. 2021 - V21
The calibrateable compact pressure sensors of the PREMASGARD® 211x / 212x / 212x - SD series are equipped with 8 switchable measuring ranges, 2 switchable output signals (16 devices in one) and with or without optional display and are used for measuring above-atmospheric, belowatmospheric, or differential pressures and Volume flow in air. The piezo-resistive measuring element is temperature-compensated and guarantees a high degree of reliability and accuracy. These pressure transmitters have a pushbutton for manual zero point calibration and an adjustable offset. Applications of these pressure sensors are in clean room, medical and filter technology, in ventilation and air conditioning ducts, in spray booths, in large-scale catering facilities, for monitoring filters, for level measurement or for triggering frequency converters. Media measured with these pressure transducers are air (non-precipitating), or other gaseous non-aggressive, non-combustible media. The differential pressure sensor is supplied including connection set ASD-06 (2 m connection hose, two pressure connection nipples, screws). You can find further device types under PREMASGARD® 111x / 112x / 112x - SD (l variant with 2-wire connection).

G PREMASGARD® 211x / 212x / 212x - SD | Configuration and zero point calibration
The following configurations can be preset via DIP switches. The DIP switch sliding blocks can be moved without using tools. DIP switch 6 is not assigned.
Pressure ranges In each case four different pressure ranges depending on the type of device can be preset via DIP switches DIP 1 and DIP 2.
Measuring range mode The measuring range is configured via DIP switch DIP 3, either into the unidirectional range or into the bidirectional range. Therefore altogether eight pressure measuring ranges are configurable.
Characteristic line analog output The output characteristic line can be defined via DIP switch DIP 4. Here is distinguished between a linear and a square root extracting output characteristic line. When square root extracting output characteristic line is selected, the measuring range setting at DIP switches DIP 1 and DIP 2 is without function. In that case the maximum pressure range is used for computation.
Offset adjustment is done at a potentiometer on the circuit board within an adjustment range of ± 10 % of the device's pressure range. Ex-factory this potentiometer is in center position and is lacquer sealed. All settings and adjustments that are made before must be done in this configuration. Offset adjustment is carried out using a tool called "screwdriver 2.5" (blade with in mm).
Automatic offset setting 1. Before setting the zero point, the device must be in operation
for at least 60 minutes. 2. Connect pressure inputs P (+) and P () by means of a hose
(pressure difference between both inputs = 0 Pa). 3. For zero point setting press "key" (auto zero) pushbutton
uninterruptedly for 5 seconds.
A LED signalises prompting the calibration by short flashing, and after a short countdown the measured (current) offset value is added to the measurand and zero voltage safe stored.
Correct calibration is confirmed by steady light of the LED for 3 seconds respectively indicated in the display (optional) by switching from "AUTO 0" to "PROG 0".
Note: By releasing the button during the countdown (counter > 0), zero point setting is immediately terminated!
Measurement signal filtering
In order to stabilize the pressure measurement signal and the output voltage, the measurement signal is filtered.
The time interval for such averaging can be preset via DIP switch DIP 5 to 1 or 10 seconds.
By a longer filtering interval, the settling time of the sensor is automatically extended.
Manual offset adjustment At the potentiometer OFFSET P can be balanced. The adjustment range is ca. ± 10 % of the pressure range. Here another reference point different from zero point can be used.
Readout in the display In the 1st line of the display, the ACTUAL pressure up to the measuring range limit is displayed. Switching between the units Pa and hPa (100 Pa = 1 hP) happens automatically. Pa = Pascal hP = Hektopascal

G General notes
This device can be mounted in any position. The voltage output is short-circuit proof. Applying overvoltage at the voltage output will destroy this device. Pressure ranges are indicated on the device label. Applying measuring pressures beyond that range will cause mismeasurements and increased deviations or may destroy the device.
Attention! When leading in cables, make sure, they do not go under the board. This might buckle or damage hose connections! The voltage output is short-circuit proof. Applying overvoltage at the voltage output will destroy this device. Pressure inputs are "poled" i.e. the above-atmospheric pressure line must be connected at input P+
and the below-atmospheric pressure line must be connected at input P. At an adjusting element, the output signal can be offset by ± 10 % of the final value of the measuring range.
In this way, possible ageing or drift effects can be compensated. Adjustment may only be made at the presence of differential pressure (ca. 90 % of final value). By changing the offset at the adjusting element, factory-calibration is lost! If this device is operated beyond the specified range, all warranty claims are forfeited.
Our "General Terms and Conditions for Business" together with the "General Conditions for the Supply of Products and Services of the Electrical and Electronics Industry" (ZVEI conditions) including supplementary clause "Extended Retention of Title" apply as the exclusive terms and conditions.

When several devices are supplied by one 24 V AC voltage supply, it is to be ensured that all "positive" operating voltage input terminals (+) of the field devices are connected with each other and all "negative" operating voltage input terminals () (= reference potential) are connected together (in-phase connection of field devices). All outputs of field devices must be referenced to the same potential!
In case of reversed polarity at one field device, a supply voltage shortcircuit would be caused by that device. The consequential short-circuit current flowing through this field device may cause damage to it.
Therefore, pay attention to correct wiring!
